Description

DETERGENT COMPOSITIONS COMPRISING ANTIBODY CONTROLLED PROTEOLYTIC ACTIVITY

FIELD of the INVENTION

BACKGROUND of the INVENTION

An important part of the system which protects vertebrates against infections by bacteria and viruses is the humoral immune system. Specialised cells present in bone marrow, lymphoid tissues and blood, produce immunoglobulins (antibody) which appear in response to the introduction of a micro- or macromolecule) foreign to that body and bind the body-foreign structure initiating its destruction. Such a body-foreign molecule is called an antigen. The antibody is directed against the antigenic determinant or hapten of the antigen e.g. an amino acid sequence, parts of oligosaccharides, polysaccharides, iipopolysaccharides, glycoproteins, lipoproteins, lipoteichoinic acids.

The specific antibodies generated in this manner can combine with the antigen which elicited their formation to form an antigen-antibody complex. Antibody molecules have binding sites that are very specific for and complementary to the structural features of the antigen that induced their formation. This highly specific antigen-antibody recognition and binding has found several applications such as recognition agent, binding agent or carrier agent in various domains such as analytical chemistry, therapeutic treatment, health and beauty care.

EP 479 600, EP 453 097 and EP 450 800 relate to the use of antibodies or fragments thereof for the delivery of active ingredients to a target site. EP 481 701 discloses treatment compositions for topical application containing microcapsules which enclose a beneficial agent at a target location, the microcapsules having an antibody or antibody fragment specific to the target location or a lectin.

WO92/04380 describes reshaped human antibody or reshaped human antibody fragments having specificity for human polymorphic epithelial mucin to be used in the treatment or diagnosis of cancer. The use of Epstein-Barr virus specific polypeptides for the production of antibodies and the diagnostic and treatment of said disease is disclosed in WO94/06470.

Oral compositions comprising antibodies as anti-carie or periodontal diseases treatment have been extensively described in WO95/01155, WO95/00110, WO95/10612, EP 140 498, GB 2 151 923, GB 2 176 400, GB 2 167 299, DE 4324859, US 5401 723 and EP 280 576.

EP 673 683 and EP 542 309 disclose hair cosmetic compositions containing an antibody to hair or hair extract, obtained from egg yolk or poultry immunised with the hair or hair extract and a polymer emulsion to provide reduced hair damage, softness, moistened feel and smoothness, said composition being adsorbed only onto a specified part of the hair.

Compositions containing antagonists (tyrphostins or antibodies) against epidermal and transforming growth factors, suitable for use in treatment of acne are described in W095/24896.

The use of antibodies in the overall detergency context has been suggested in Unilever Researchprijs "Molecule zoekt partner" 1992 wherein modofied antibodies directed to specific stains are proposed to be used in bleaching process.

The production of antibodies by hyperimmunisation of mammals such as a cow with a vaccine derived from E. coli bacteria is described in EP 102 831. EP 400 569 discloses a method for preparing vaccine composition for dental caries in nasal drops comprising an antigen produced by integrating a protein antigen- expressing gene into the chromosomal gene of a streptococcus mutants GS-5 strain. W094/25591 discloses the production of antibodies or functionalised fragments thereof derived from heavy chain immunoglobulins of camelidae.

Detergent compositions include nowadays a complex combination of active ingredients which fulfill certain specific needs : a surfactant system, enzymes providing cleaning and fabric care benefits, bleaching agents, a builder system, suds suppressors, soil-suspending agents, soil-release agents, optical brighteners, softening agents, dispersants, dye transfer inhibition compounds, abrasives, bactericides, perfumes, and their overall performance has indeed improved over the years.

In particular, current laundry detergent formulations generally include detergent enzymes and more specifically proteases.

However, overexposure of the substrate to the proteolytic activity and/or transfer of the proteolytic activity to the post mainwash part of the washing cycle such as rinse, spinning and/or drying steps can lead to unwanted effects. It is well known that the detergent proteolytic enzymes can under certain circumstances lower the tensile strength of the wool constituants of fabrics. It should be noted however, that tensile strength loss of fabric is also an unavoidable result of mechanical action due to use/wearing and may further result from damage by a bleaching component in the laundry process, especially if the fabric is contaminated with metal compounds.

It has now been surprisingly found that the application of antibodies raised against the proteolytic enzyme prevents the occurrence of undesirable residual proteolytic activity. The proteolytic activity can be fully controlled during the cleaning process so that the negative effects due to the overexposure of the substrate to the proteolytic enzyme can now be avoided. It is therefore an object of the present invention to provide a protease- containing laundry detergent composition delivering excellent cleaning benefits such as stain and/or soil removal, dingy cleaning and fabric care benefits.

The above need has been met by specific laundry detergent compositions comprising a protease and an antibody directed to said proteolytic enzyme.

SUMMARY of the INVENTION

The present invention relates to laundry detergent compositions comprising a protease enzyme and an antibody raised against the proteolytic enzyme in order to provide excellent cleaning performance and fabric care performance.

DETAILED DESCRIPTION of the INVENTION

ANTIBODY

An essential element of the detergent compositions of the present invention is an antibody.

The immunoglobulins are classified into 5 classes, respectively : IgM, IgG, IgA, IgD and IgE. Preferred types of immunoglobulins are IgG and IgA. Secretory slgA which are found into human excreted body fluids such as milk, saliva, respiratory and intestinal fluids are especially designed to survive in said secretions, they have enhanced binding characteristics and are resistant to proteolytic hydrolysis.

The antibody which may be monoclonal or polyclonal or an antibody fragment, may be generated by techniques conventional in the art, for example by using recombinant DNA techniques allowing to produce antibodies variants with new properties : reduced immunogenecity, enhanced affinity, altered size, ... Specific binding may also be used. Preferred for the purpose of the present invention is a monoclonal antibody, more preferred is a fragment thereof. These fragments may be similarly generated by conventional techniques such as enzymatic digestion by papain or pepsin, or using recombinant DNA techniques. Antibody fragments may also be generated by conventional recombinant DNA techniques. Antibodies and antibodies' fragments may be humanised, such as described in Meded. - Fac. Landbouwkd. Toegepast Biol. Wet. (Univ. Gent) (1995), 60(4a, Forum for Applied Biotechnology, 1995, Part 1), 2057-63.

Heavy and light chains are indeed composed of constant and variable domains. In the organisms producing immunoglobulins in their natural state the constant domains are very important for a number of functions, but for many applications in industrial processes and products their variable domains are sufficient. Consequently many methods have been described to produce antibody fragments.

Antibody fragments which are used may be a Fab, a Fv, a scFv or any other fragment having similar binding properties. Preferred routes to antibodies fragments are through recombinant DNA technology, so that the fragment is expressed by a genetically transformed organism.

Antibodies and antibody fragments produced by recombinant DNA technology do not need to be identical to fragment of antibodies produced in vertebrates, having nevertheless the same binding properties evaluated by their Km, Ki and Kcat For instance they may include sequences of amino acids and/or gly cosy lations which differ from those found in antibodies produced in other ways, especially sequences at the ends of fragments. Somewhat analogously, antibody fragments produced through recombinant DNA technology may include extra amino acid sequences at their termini which have no counterpart in antibodies produced in other ways.

A related possibility is that a binding agent for use in this invention is a natural or synthetic polymer which mimics the specific binding activity of a natural antibody's complementary region(s). Such a polymer is for example a polypeptide or a polymer imprinting (Arigew. Chem. Int. Ed. Engl. 1995, 34, 1812-1832). The usual method for the production of antibodies may be adopted in immunising mammals or poultry with the corresponding antigens. As mammals to be immunised, mice, rabbits, goats, sheep, horses, cows, etc. may be used. The antibody (immunoglobulin fraction) may be separated from the antiserum, the milk or the eggs according to the ordinary antibody purification method including salting-out method, Poison extraction, gel-filtration chromatography, ion- exchange chromatography, affinity chromatography and the like, the salting-out method using ammonium sulfate to produce the precipitates, followed by dialysing the precipitates against physiological saline to obtain the purified precipitates as the antibody.

Plants are also capable of synthesising and assembling every kind of antibody molecule and allow a large scale of production of antibodies as described in Tibtech. Dec 1995, Vol 13, pp 522-527; Plant Mol. Biol., 26, pp 1701-1710, 7994 and Biotechnol. proj. 1991, 7, pp 455-461 and in US patent 5, 202,422. Antibodies can also be produced into microorganisms such as E. coli or S. cerevisiae via biofermentation process as illustrated in the EP patent 667 394.

Techniques for the production of antibody fragments are well known in the literature : Saiki et al. Science 230 1350-54 (1985); Orlandi et al. PNAS USA 86 3833-7 (1989); WO89/09825; EP 368 684; WO 91/08482 and W094/25591.

The drawbacks due to prolonged activity of the enzyme can be avoided by an effective control of the enzymatic activity trough the introduction of the specifically corresponding antibody. Such antibodies can be either polyclonal - directed to the whole enzyme structure - or monoclonal - directed to specific epitopes of the enzyme activity controlling regions of the enzyme structure. Antibodies raised against specific enzyme can effectively deactivate the enzyme by the antibody-antigen binding in or very near the active site. The formation of such complex leads to the enzyme deactivation and could be explained by the distortion of the 3-dimensional structure and/or steric hindrance at the substrate cleft. The deactivation of the enzyme can also be achieved by the precipitation of the complex antibody-antigen from the washing solution. Due to very high specificity and efficiency of the antibody-antigen interaction, no other detergent active is thereby affected. The protease-directed antibodies are preferably included into the detergent compositions of the present invention at a level of from 10E-6% to 10E+1% by weight of total composition. In some instances, antibodies raised against specific proteases have the capability of binding other proteases of high structural similarity, providing cross-reactivity. Typically, a molecular ratio of protease-directed antibody to protease will be of 100:1 or lower, preferably of 50:1 or lower. For monoclonal antibodies or fragments thereof, the molecular ratio of protease-directed antibody to protease will be generally of 50:1 or lower, preferably of 20:1 or lower.

The antibodies raised against the protease are released in the wash solution after a lag-period allowing the protease to deliver excellent performance benefits to be achieved by the end of the wash process.

Therefore, the antibodies are preferably incorporated into a release agent in order to control their release timing and rate in the wash solution. The physical form of the antibody-containing release agent is adapted to the physical form of the corresponding detergent or additive.

For granular and powder detergent and cleaning products, the antibodies and release agents can be contained in a granulate. Said antibody granulate can suitably contain various granulation aids, binders, fillers, plasticizers, lubricants, cores and the like. Examples thereof include cellulose (e.g. cellulosic fibers or in microcrystalline form), cellulose derivatives (CMC, MC, HPC, HPMC), gelatin, starch, dextrins, sugars, polyvinylpyrrolidone, PVA, PEG, salts (e.g. sodium sulfate, calcium sulfate), titanium dioxide, talc, clays (kaolin or bentonite)and nonionic surfactants. Other materials of relevance for incorporation in the granulate are described in EP 304 331.

The release agent may be, for example, a coating. Said coating protects said granulates in the wash environment for a certain period of time. The coating will normally be applied to said granulates in an amount in the range of 1% to 50% by weight (calculated on the basis of the weight of the uncoated, dry granulate), preferably in the range of 5 % to 40 % by weight. The amount of coating to be applied to said granulates will depend to a considerable extent on the nature and composition of the desired coating, and to the kind of protection said coating should offer to said granulates. For example, the thickness of said coating or a multi-layered coating applied onto any of the above granulates may determine the period in which the content of said granulates is released. A possible multi-layered coating may be a coating in which, for example, a fast release coating is applied over a slow release coating.

Also co-granulates can be constructed containing in the outer layer the detergent enzyme and a fast releasing agent and in the inner core, the antibody and a slow releasing agent.

Suitable release coatings are coatings which give rise to release of the contents of antibody-containing granulates under the conditions prevailing during the use thereof. Thus, for example, when a preparation of the invention is to be introduced into a washing liquor containing a washing detergent (normally comprising, e.g. one or more types of surfactants), the coating should be one which ensures the release of the contents of said granulates from the release agent when it is introduced into the washing medium.

Preferred release coating are coatings which are substantially insoluble in water. Release coatings which are appropriate in washing media may suitably comprise substances selected from the following: cellulose and cellulase derivatives, PVA, PVP, tallow; hydrogenated tallow; partially hydrolyzed tallow; fatty acids and fatty alcohols of natural and synthetic origin; long-chain fatty acid mono-, di- and triesters of glycerol (e.g. glycerol monostearate); ethoxylated fatty alcohols; latexes; hydrocarbons of melting point in the range of 50-80°C; and waxes. Melt-coating agents are a preferred class of fast or slow release coating agents which can be used without dilution with water. Reference may be made to Controlled Release Systems : Fabrication Technology, Vol. I, CRC Press, 1988, for further information on slow release coating.

Coatings may suitably further comprise substances such as clays (e.g. kaolin), titanium dioxide, pigments, salts (such as calcium carbonate) and the like. The person skilled in the art will be aware of further coating constituents of relevance in the present invention. In liquid detergent compositions, the antibody can be incorporated as a dispersion of particles containing in addition to the antibody, a release agent. The antibody can be present in a liquid or solid form. Suitable particles consist of a porous hydrophobic material (e.g., silica with an average pore diameter of 500 Angstrom or higher) containing into the pores a solution of antibodies and a surfactant as described in EP 583 512 of Surutzidis A. et al. The release agent might be a coating which protects said particles in the wash cycle for a certain period of time. The coating is preferably a hydrophobic coating material such as a hydrophibic liquid polymer. Said polymer can be an organo polysiloxane oil, alternatively a high olecula weight hydrocarbon or water insoluble but water permeable polymeric material such as carboxymethylcellulose, PVA, PVP. The polymer properties are selected to achieve a suitable release profile of the antibody in the wash solution.

THE PROTEASE ENZYME

The proteolytic enzymes are incorporated in the detergent compositions of the present invention at a level of from 0.0001% to 2%, preferably from 0.001% to 0.2%, more preferably from 0.005% to 0.1% pure enzyme by weight of the composition.

The proteolytic enzyme can be of various origin, e.g. produced by mammals, plants, microorganisms. Origin can further be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halophilic, etc.). Microorganisms are preferred producers of proteolytic enzymes. Very preferred are serine proteases of bacterial origin. Purified or non-purified forms of these enzymes may be used. Also included by definition, are mutants of native enzymes. Mutants can be obtained e.g. by protein and/or genetic engineering, chemical and/or physical modifications of native enzymes. Common practice as well is the expression of the enzyme via host organism in which the genetic material responsible for the production of the enzyme has been cloned.

Suitable proteases are the subtilisins which are obtained from particular strains of B. subtilis and B. licheniformis (subtilisin BPN and BPN'). One suitable protease is obtained from a strain of Bacillus, having maximum activity throughout the pH range of 8-12, developed and sold as ESPERASE® by Novo Industries A/S of Denmark, hereinafter "Novo". The preparation of this enzyme and analogous enzymes is described in GB 1 ,243,784 to Novo. Other suitable proteases include ALCALASE®, DURAZYM® and SAVINASE® from Novo and MAXATASE®. MAXACAL®, PROPERASE® and MAXAPEM® (protein engineered Maxacal) from Gist-Brocades. Proteolytic enzymes also encompass modified bacterial serine proteases, such as those described in European Patent Application Serial Number 87 303761.8, filed April 28, 1987 (particularly pages 17, 24 and 98), and which is called herein "Protease B", and in European Patent Application 199,404, Venegas, published October 29, 1986, which refers to a modified bacterial serine protealytic enzyme which is called "Protease A" herein. Suitable is the protease called herein "Protease C", which is a variant of an alkaline serine protease from Bacillus in which lysine replaced arginine at position 27, tyrosine replaced valine at position 104, serine replaced asparagine at position 123, and alanine replaced threonine at position 274. Protease C is described in EP 90915958:4, corresponding to WO 91/06637, Published May 16, 1991. Genetically modified variants, particularly of Protease C, are also included herein.

A preferred protease referred to as "Protease D" is a carbonyl hydrolase variant having an amino acid sequence not found in nature, which is derived from a precursor carbonyl hydrolase by substituting a different amino acid for a plurality of amino acid residues at a position in said carbonyl hydrolase equivalent to position +76, preferably also in combination with one or more amino acid residue positions equivalent to those selected from the group consisting of +99, +101 , +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274 according to the numbering of Bacillus amyloliquefaciens subtilisin, as described in WO95/10591 and in the patent application of C. Ghosh, et al, "Bleaching Compositions Comprising Protease Enzymes" having US Serial No. 08/322,677, filed October 13, 1994.

Also suitable for the present invention are proteases described in patent applications EP 251 446 and WO 91/06637, protease BLAP® described in WO91/02792 and their variants described in WO 95/23221. See also a high pH protease from Bacillus sp. NCIMB 40338 described in WO 93/18140 A to Novo. Enzymatic detergents comprising protease, one or more other enzymes, and a reversible protease inhibitor are described in WO 92/03529 A to Novo. When desired, a protease having decreased adsorption and increased hydrolysis is available as described in WO 95/07791 to Procter & Gamble. A recombinant trypsin-like protease for detergents suitable herein is described in WO 94/25583 to Novo. Other suitable proteases are described in EP 516200 by Unilever.

The composition of the present invention can also includes protease enzymes which are non-naturally-occurring carbonyl hydrolase variants having a different proteolytic activity, stability, substrate specificity, pH profile and/or performance characteristic as compared to the precursor carbonyl hydrolase from which the amino acid sequence of the variant is derived. As stated earlier, the protease enzymes are designed to have trypsin-like specificity and preferably also be bleach stable. The precursor carbonyl hydrolase may be a naturally- occurring carbonyl hydrolase or recombinant hydrolase. Specifically, such carbonyl hydrolase variants have an amino acid sequence not found in nature, which is derived by replacement of a plurality of amino acid residues of a precursor carbonyl hydrolase with different amino acids. The plurality of amino acid residues of the precursor enzyme correspond to position +210 in combination with one or more of the following residues: +33, +62, +67, +76, +100, +101, +103, +104, +107, +128, +129, +130, +132, +135, +156, +158, +164, +166, +167, +170, +209, +215, +217, +218, and +222, where the numbered position corresponds to naturally-occurring subtilisin from Bacillus amyloliquefaciens or to equivalent amino acid residues in other carbonyl hydrolases or subtiiisins, such as Bacillus lentus subtilisin.

The carbonyl hydrolase variants which are protease enzymes useful in the present invention compositions comprise replacement of amino acid residue +210 in combination with one or more additional modifications. While any combination of the above listed amino acid substitutions may be employed, the preferred variant protease enzymes useful for the present invention comprise the substitution, deletion or insertion of amino acid residues in the following combinations: 210/156; 210/166; 210/76; 210/103; 210/104; 210/217 210/156/166; 210/156/217; 210/166/217; 210/76/156; 210/76/166; 210/76/217

210/76/156/166; 210/76/156/217 210/76/166/217 210/76/103/156 210/76/103/166; 210/76/103/217 210/76/104/156 210/76/104/166 210/76/104/217; 210/76/103/104/156 210/76/103/104/166 210/76/103/104/217 210/76/103/104/156/166; 210/76/103/104/156/217; 210/76/103/104/166/217 and/or 210/76/103/104/156/166/217; 210/76/103/104/166/222;

210/67/76/103/104/166/222; 210/67/76/103/104/166/218/222. Most preferably the variant enzymes useful for the present invention comprise the substitution, deletion or insertion of an amino acid residue in the following combination of residues: 210/156; 210/166; 210/217; 210/156/166; 210/156/217; 210/166/217; 210/76/156/166; 210/76/103/156/166 and 210/76/103/104/156/166 of B. lentus subtilisin with 210/76/103/104/156/166 being the most preferred.

Variant DNA sequences encoding such carbonyl hydrolase or subtilisin variants are derived from a precursor DNA sequence which encodes a naturally- occurring or recombinant precursor enzyme. The variant DNA sequences are derived by modifying the precursor DNA sequence to encode the substitution of one or more specific amino acid residues encoded by the precursor DNA sequence corresponding to positions +210, +33, +62, +67, +76, +100, +101, +103, +104, +107, +128, +129, +130, +132, +135, +156, +158, +164, +166, +167, +170, +209, +215, +217, +218, and +222 in Bacillus lentus or any combination thereof. Although the amino acid residues identified for modification herein are identified according to the numbering applicable to B. amyloliquefaciens (which has become the conventional method for identifying residue positions in all subtilisins), the preferred precursor DNA sequence useful for the present invention is the DNA sequence of Bacillus lentus. These recombinant DNA sequences encode carbonyl hydrolase variants having a novel amino acid sequence and, in general, at least one property which is substantially different from the same property of the enzyme encoded by the precursor carbonyl hydrolase DNA sequence. Such properties include proteolytic activity, substrate specificity, stability, altered pH profile and/or enhanced performance characteristics.

The protease enzymes useful herein encompass the substitution of any of the nineteen naturally occurring L-amino acids at the designated amino acid residue positions. Such substitutions can be made in any precursor subtilisin (procaryotic, eucaryotic, mammalian, etc.). Throughout this application reference is made to various amino acids by way of common one- and three-letter codes. Such codes are identified in Dale, M.W. (1989), Molecular Genetics of Bacteria. John Wiley & Sons, Ltd., Appendix B.

Preferably, the substitution to be made at each of the identified amino acid residue positions include but are not limited to substitutions at position +210 including I, V, L, and A, substitutions at positions +33, +62, +76, +100, +101 , +103, +104, +107, +128, +129, +130, +132, +135, +156, +158, +164, +166, +167, +170, +209, +215, +217, and +218 of D or E, substitutions at position 76 including D, H, E, G, F, K, P and N; substitutions at position 103 including Q, T, D, E, Y, K, G, R and S; and substitutions at position 104 including S, Y, I, L, M, A, W, D, T, G and V; and substitutions at position 222 including S, C, A. The specifically preferred amino acid(s) to be substituted at each such position are designated below in Table I. Although specific amino acids are shown in Table I, it should be understood that any amino acid may be substituted at the identified residues.

The polyamine oxides can be obtained in almost any degree of polymerisation. The degree of polymerisation is not critical provided the material has the desired water-solubility and dye-suspending power.

Typically, the average molecular weight is within the range of 500 to 1000,000; preferably from 1,000 to 50,000, more preferably from 2,000 to 30,000, most preferably from 3,000 to 20,000.

b) Copolymers of N-vinylpyrrolidone and N-vinylimidazole

The N-vinylimidazole N-vinylpyrrolidone polymers used in the present invention have an average molecular weight range from 5,000-1,000,000, preferably from 5,000-200,000.

Highly preferred polymers for use in detergent compositions according to the present invention comprise a polymer selected from N-vinylimidazole N- vinylpyrrolidone copolymers wherein said polymer has an average molecular weight range from 5,000 to 50,000 more preferably from 8,000 to 30,000, most preferably from 10,000 to 20,000.

The average molecular weight range was determined by light scattering as described in Barth H.G. and Mays J.W. Chemical Analysis Vol 113, "Modern Methods of Polymer Characterization".

Highly preferred N-vinylimidazole N-vinylpyrrolidone copolymers have an average molecular weight range from 5,000 to 50,000; more preferably from 8,000 to 30,000; most preferably from 10,000 to 20,000.

The N-vinylimidazole N-vinylpyrrolidone copolymers characterized by having said average molecular weight range provide excellent dye transfer inhibiting properties while not adversely affecting the cleaning performance of detergent compositions formulated therewith.

The N-vinylimidazole N-vinylpyrrolidone copolymer of the present invention has a molar ratio of N-vinylimidazole to N-vinylpyrrolidone from 1 to 0.2, more preferably from 0.8 to 0.3, most preferably from 0.6 to 0.4 . c) Polyvinylpyrrolidone

Said polyvinyloxazolidones have an average molecular weight of from about 2,500 to about 400,000, preferably from about 5,000 to about 200,000, more preferably from about 5,000 to about 50,000, and most preferably from about 5,000 to about 15,000.

e) Polyvinylimidazole :

The detergent compositions of the present invention may also utilize polyvinylimidazole as polymeric dye transfer inhibiting agent. Said polyvinylimidazoles have an average about 2,500 to about 400,000, preferably from about 5,000 to about 200,000, more preferably from about 5,000 to about 50,000, and most preferably from about 5,000 to about 15,000.

f) Cross-linked polymers : Cross-linked polymers are polymers whose backbone are interconnected to a certain degree; these links can be of chemical or physical nature, possibly with active groups n the backbone or on branches; cross-linked polymers have been described in the Journal of Polymer Science, volume 22, pages 1035-1039.

In one embodiment, the cross-linked polymers are made in such a way that they form a three-dimensional rigid structure, which can entrap dyes in the pores formed by the three-dimensional structure. In another embodiment, the cross- linked polymers entrap the dyes by swelling.

Such cross-linked polymers are described in the co-pending patent application 94870213.9

Example 1 :

Antibodies' production:

Chickens were injected in the breast muscle with 1 ml of a 1 mg/ml Savinase® or Alcalase® emulsion. The proteolytic emulsion was prepared with a Freunds completed adjuvants (Freund and McDermott, 1942; Freund 1956) by intensively mixing an equal amount of Savinase® or Alcalase® solution (2 mg/ml) and Freunds complete adjuvant.

The immunisation scheme was completed with injections using a Freunds uncomplete adjuvant and after a 4 weeks period, the eggs were collected during one week. The extraction of the antibodies from the eggs yolks was done according to the Poison extraction method as described in Immunological Investigation 19, 1990, pp 253-258.

Protease enzymatic inactivation :

A Savinase® or Alcalase® stock solution was prepared in a Tris Buffer (5x10^_2M Tris, 25 mM NaCl, pH=8) at a concentration of 0.05% active enzyme. A Phosphate Buffer (0.05M KH2P04, pH 6.8)contained the antibody (0.18 mg/ml). The interaction proteolytic enzyme (Final concentration 0.004%) / antibody was achieved in commercially available detergent solutions comprising Ariel liquid (0.8% in city water, pH 8.5) and Ariel Color Futur(0.8% in city water, pH 9.5) during 15 minutes at 40°C.

The proteolytic residual activity was measured according the method described in Deimar et al.(1979) Anal. Biochem. 99, pp316-320. Within 5 minutes the enzymatic activity of the protease was successfully blocked as shown in the table below. Residual proteolytic activity
