Definitions
- the invention relates to an immunoassay kit for the qualitative and quantitative determination of a sample by -specifically-binding binders such as - - ⁇ - B - - - Anti-kerper- 7 - -A t -ige-ne -, - receptors and ligands, with a carrier plate or a microtiter plate with a plurality of wells, the carrier plate or the microtiter plate being precoated with a primary binding partner and the binding partner being fixed as a lyophilisate.
- binders such as - - ⁇ - B - - - Anti-kerper- 7 - -A t -ige-ne -, - receptors and ligands
- Immunoassays enzyme-linked immunoassays, fluorescence-label-linked immunoassays, luminescence-label-linked immunoassays or immunoassays labeled with another label are used in routine diagnostics and research diagnostics for the detection and quantification of proteins, e.g. antigens, ligands, receptors, antibodies and chemical compounds .
- the state of the art in such test kits is to bind one of the binding partners to a solid support, for example a polystyrene plate, and the other reagents required for carrying out the test as separate. Add components of the test kit.
- reagents are usually the protein to be detected in quantified form as concentrate or lyophilisate (reference standard), a standard and sample dilution medium, the second specific binding partner in coupled form (conjugate) as concentrate or working solution, if required a secondary detection system and in the case of an enzyme label this substrate reagent required for detection.
- a stop solution is added to terminate the enzymatic reaction, and an assay buffer, which is usually present as a concentrate, is available to prepare the working solutions for the second specific binding partner and for the secondary reagent. Since washing steps are required between the work steps, a conventional immunoassay kit contains a washing buffer, usually in a concentrated form.
- Commercial ELISA kits offer the user validated test systems.
- the products contain all the reagents required for carrying out the test in optimized concentrations and amounts as well as a detailed protocol for carrying out • the - test -. the - usual-white e-consecutive carried out.
- the common incubation of analytes (standard, sample) and secondary antibody with the solid phase (cocktail) is possible for a large number of test systems.
- a typical example of an immunoassay is the sandwich ELISA (enzyme linked immunosorbent assay).
- Such ELISA kits typically contain the following components:
- Reference material analyte (standard) in a defined concentration to create a standard series
- Assay buffer saline solution for diluting the secondary antibody and streptavidin enzyme concentrate (preparation of working solutions)
- Sample dilution medium Specific liquid medium for dilution of the reference material and the unknown samples
- the invention now aims to simplify the handling of such test kits and, in addition to a qualitative statement, also to enable quantitative statements to be made.
- the invention also aims to reduce the likelihood of errors for the user by minimizing the work steps to be carried out.
- the aim of the present invention is to reduce the packaging volumes and packaging costs as well as the shipping costs by significantly reducing the weight and volume of the kits and to provide a logistical simplification in which standardized basic kits are provided with improved shelf life of the product.
- the immunoassay kit according to the invention essentially consists in that a reference standard series of the sample to be determined with incremental dilution in lyophilized form is additionally present in part of the wells of the microtiter plate.
- a reference standard series of the sample to be determined with incremental dilution in lyophilized form is additionally present in part of the wells of the microtiter plate.
- the prefabrication of the immunoassay kit can be pushed much further and the necessary determination steps for the sample can be further reduced.
- the design is advantageously made such that the wells of the microtiter plate additionally contain an enzyme or biotin-coupled conjugate of a secondary binding partner, in particular an antibody, and in the case of the biotin-coupled conjugate, an enzyme in lyophilized form.
- the second specific binding partner conjugate in titrated concentration and, if necessary, the secondary reagent coupled with one of the above-mentioned labels is also used for detection together with the primary binding partner which is firmly bound to phases already introduced in lyophilized form in the solid phase, the provision of these components in lyophilized form, i. H . thus in a form dehydrated at low temperatures of about -30 ° C., the reaction kinetics freeze to such an extent that there is no fear of a preliminary reaction of the reference material. Because highly diluted working solutions just as limited stable solutions are not kept in stock, but rather are generated on the carrier immediately after the start of the test by adding solvent or rehydration, further possible sources of error are excluded.
- the design is such that the wells of the microtiter plate contain a sample dilution medium in lyophilized form.
- the specific sample dilution medium can be introduced into the corresponding wells of the microtiter plate at a temperature of, for example, 2 ° C., the secondary antibody-enzyme conjugate or the mixture of secondary antibody-biotin conjugate being able to be introduced into all wells of the microtiter plate at the same temperature , whereupon the microtiter plate charged in this way is subjected to a lyophilization in a freeze-drying process in a freeze-dryer, for example, which has been pre-cooled to -30 ° C.
- Such a prefabricated carrier or such a prefabricated microtiter plate only requires a small number of additional components to complete the test kit, the test kit advantageously containing only washing buffer, substrate solution and stop solution in addition to the precoated microtiter plate.
- the test kit advantageously containing only washing buffer, substrate solution and stop solution in addition to the precoated microtiter plate.
- For the determination of the sample it is therefore only necessary to rehydrate the microtiter plate by adding defined volumes of distilled water to the wells of the standard series, if necessary the blanks and the sample wells, whereupon the unknown sample is added and incubated.
- the stop solution is added after a predetermined time and the test evaluation can be carried out immediately.
- the training is advantageously made such that streptavidin - horse radical peroxidase (HRP) is used as the secondary reagent in the case of biotin-coupled secondary antibody conjugate.
- HRP horse radical peroxidase
- test execution for the user is reduced to the addition of the unknown sample and the enzymatic reaction by the inventive design, all further steps being carried out beforehand by the manufacturer of the ELISA kit.
- the microtiter plate is thus coated, blocked and fixed at the manufacturer with the specific primary antibody, whereupon the plate is cooled, for example, to -20 ° C. and the additional steps described above for introducing the standard series of the sample diluent and the secondary antibody-enzyme conjugate or the mixture made of secondary antibody-biotin conjugates and streptavidin enzyme in a defined manner at the manufacturer.
- the test procedure is therefore reduced to the addition of the samples to be analyzed and the test evaluation based on the substrate staining.
- the immunoassay kit according to the present invention is designed such that the test kit stabilizers for peroxidase or general lyoprotectants such as proteins (e.g. albumin (e.g. BSA) protein hydrolysates (peptones, gelatin ...) casein), Polymers (e.g. dextran, PVA, PVP), sugar (e.g. sucrose, trehalose, lactose, xylitol, sorbitol, mannitol, maltose, glucose, inositol), bacteriostatic agents (e.g.
