I One-Way Reaction Vessel for the Solid-Phase Immunological Analysis of, and a Method of Measuring Constituents which can be determined via Immune Reactions Description The present invention concerns a disposable reaction vessel for the solid-phase immune analysis, and a method for its application.
Affinity chromatography is a technology which is broadly applied in preparative purification of bio-molecules. Therein, advantage is taken of a specific interaction between the molecule to be determined and a complementary binding partner. In the general practice of such methods, a sample containing the bio-molecule to be purified is applied to a chromatographic column, which contains one of the mutually complementary binding partners bound to a solid substrate. Examples of pairs of complementary binding partners are enzymes and their substrates, antibodies and hapten r-es. antigen, and mutually complementary DNA or RNA single chains.
In immunoaffinity chromatography, for quantification use is made of the interaction between an antigen p. a hapten and the complementary antibody.
Up to now, in immunoassays using affinity chromatography, reusable columns are generally used which are packed with the antibody or antigen (named ligand in the following) bound to a solid substrate. The sample to be analyzed is pressed through the chromatographic column by high pressure to guarantee a rapid chromatographic processing. The application of high-pressure liquid chromatography (HPLC) for immunoassays is described e.g. by de Elvis, and Wilson, in "Analytical Chemistry", 1985, Vol. 57, pp. 2754-2756, and Sportsman, J.R. et al. in "Analytical Chemistry", 1983, Vol. 55, pp. 771-775. However, the use of HPLC for immunoassays has several drawbacks. On the one hand, the use of costly instruments is necessary for this technique, and on the other hand, the chromatographic columns for the analysis must meet high technical demands. The columns must withstand the high pressures applied in HPLC as well as be reusable to allow a rational application of this technology. However, the reuse of the columns requires additional measures before a new sample can be analyzed on the same column. As published in DE-OS 37 11 894, reusable columns are regenerated prior to every analysis to prevent effects of displaced and incompletely eluted substances of the previous test.
2 In the DE-OS 24 48 411 a reaction vessel is described for solidphase immune analysis. However, prior to a quantitative determination, this vessel for multiple use requires a calibration with standards of the component to be determined. Besides, long incubation times are necessary in this described reaction vessel, during which the flow through the column is stopped. 6 hours to 2 days are recommended to guarantee sufficient binding of the component to be determined to the immunologically complementary binding partner loaded onto the substrate. However, the binding reaction is always terminated before the binding equilibrium is reached, which would take 1-2 days, to guarantee a rational performance. The requirement of calibration with standard solutions is a consequence as well of this early termination of the binding reaction.
According to the preference in practice for disposable columns, the DE-PS 26 26 823 describes a procedure for the preparation of a prefabricated disposable adsorption column especially for radio immunoassays using analytical instruments applying centrifugal forces. However, this column is not a reaction column, and is useful for the separation after an immune reaction only, because it is not loaded with a specific immunoreactive component. To prevent disturbing effects during the separation via gel bed, the flow resistance of the porous retaining devices is kept as low as possible.
The object of the present invention is to provide a disposable reaction vessel for the solid-phase immune analysis which allows the rapid direct performance of immunoassays, which is easy to handle, and which is ready to immediate use without prior calibration or regeneration, and a method for the application of this vessel.
With respect to the device, this is accomplished in the present invention by a disposable reaction vessel for the solid-phase immune analysis which is open at the upper and lower ends, in which at least one immunologically reactive component is bound to a substrate, characterized by a substrate bed volume of up to 600 p1) and by the determination of the liquid flow velocity by the permeability of the substrate. The substrate is either a solid frit, membraneor the like, or it is contained between an upper and a lower separating device.
With respect to the method, this is accomplished by a procedure for the determination of components which can be determined via immune reactions, which is characterized by the application of the sample to be analyzed to a disposable reaction vessel according to any one of the claims 1-20, which is further characterized by the retention of the sample component, which has to be determined, by the complementary immunologically reactive component in the disposable reaction vessel during the direct flow-through, and in which the component to be determined is 3 a) eluted and determined, or b) labelled in the disposable reaction vessel via amplification reactions with common immunological markers, and then determined, or c) determined via a labelled compound in reactive competition to the component to be determined.
The invention is described in detail with relation to figures 1 and 2 which show: Fig. la a longitudinal section of a disposable reaction vessel 1 according to the invention containing two separating devices 2a and 2b, bptween which the substrate with the immunologically reactive component 3 is located, Fig. Ib a top view of the disposable reaction vessel 1, 15 and Fig. 2 a scheme of an online-system for antibody production control.
The dimensions given in figures la and Ib are for example only.
20 The described disposable reaction vessel 1 and the described method, in which the disposable reaction :vessel 1 is used, exhibit several considerable advantages compared to known reaction vessels or methods.
The described disposable reaction vessel 1 allows a rapid performance of the quantitative determination of components which can be determined by immunoreactions. The handling of the reaction vessel 1 is very simple and does not require the use of costly instruments such as HPLC apparatus. In addition, excellent results are obtained with the aforesaid disposable reaction vessel 1 at extremely low consumption of substrate 3 with bound immunologically reactive component (named substrate bed in the following). A disposable reaction vessel 1 with a substrate bed volume 8, i.e. the volume between the upper and lower separating device 2a and 2b, of 50 il is preferably used. The small substrate bed volume allows the statt/aelkeeptspec36316.93_1 2.596 4 use of small quantities of elution liquid with the consequence that the dilution effect of the elution remains small, and thus the detection limit is not decreased in contrast to other methods in which larger elution volumes are necessary.
Besides, the aforesaid reaction vessel 1 allows the quantitative determination at binding equilibrium (endpoint determination) between the component to be determined and the immunologically reactive component. The binding equilibrium is reached within an incubation time of 1 minute already in the aforesaid disposable reaction vessel 1.
The rapid equilibration is rendered possible by the small substrate bed volume 8, its flow resistance, and 15 the high loading of the substrate with the immunologically reactive component. The consequence of the controlled flow and the high loading of the substrate with the reactive component is that the component to be determined is bound quantitatively to the reactive component within about 1 minute, i.e. before the flowing liquid leaves the substrate bed volume. Therefore, a comparative analysis with standard references need not be made.
""Besides, a rapid analysis of samples is possible, because the disposable reaction vessel 1 allows immediate use, because the substrate 3 with the immunologically reactive component can be standardised and ready-made, and the disposable reactio; vessel 1 does not need to be calibrated before use.
The substrate 3 does not need to be stable against pressure, because the disposable reaction vessel 1 allows the rapid analysis of samples without application of HPLC. For the substrate 3, all common materials useful for affinity chromatography can be considered. Preferred substrate materials are polymeric sugars, plastics, plastic-modified substrates, metal oxides such as aluminium oxide, titanium dioxide or zirconium oxide, or silicates.
staff/ae/eep/speci/36316.93_1 2.5.96 5 Substrate materials in the form of frits are especially preferred. For the determination of very large components such as viruses, which do not have access to the pores of such substrate materials, graft copolymers with side chains with active groups are preferred.
Preferably, the graft copolymer is polyethylene glycol grafted to polystyrene and having a particle size of to The immunologically reactive component loaded onto the substrate material 3 can be bound to the substrate material covalently as well as adsorptively. The immunologically reactive component can be selected from the group containing haptens, antigens, antibodies, and immunoaffinity proteins. Polyclonal as well as monoclonal 15 antibodies can be used.
The substrate 3 may have a porosity of 0.21pn to 100pm and a layer thickness of 0.1 mm to 20 mm.
The vessel material 4 does not need to be stable against pressure, because the disposable reaction vessel 1 S 20 does not need to be subjected to high pressures in the present procedure. Therefore, besides pressure-resistant materials such as metals, other non-pressure-resistant materials can be considered for the production of the S: disposable reaction vessel 1 such as glass, natural materials, and plastics. Preferred plastics are polyethylene, polypropylene, and/or polystyrene, and preferred metals are aluminium and stainless steel.
For practical purposes, the disposable reaction vessel 1 has a swelling 5 at one end to allow adaption of the reaction vessel into a holding and moving device for automatic transport. This is necessary for the use in automated sample processing devices.
For practical purposes, the disposable reaction vessel 1 can have a smaller diameter at the end opposite to the swelling, preferably for joining a socket-switch connection with another disposable reaction vessel. This staffaeeepspeciV36316.93.1 2.5.96 5a facilitates e.g. joining in series of several disposable reaction vessels 1, whereby the outlet 6 of the first vessel is connected with the inlet of the second vessel by an easy simple male-female connection.
In a preferred embodiment, the disposable reaction vessel 1 is closable by caps 7 and 9.
The present procedure using said disposable reaction vessel 1 is superior due to, among others, a strongly simplified p- ,cedure compared to common procedures, and because it allows a rapid quantitative and qualitative determination. This is enabled partly because the determination of the component to be determined does not require a preceding calibration or regeneration of the used substrate in the disposable reaction vessel 1, and S 15 because no series reference measurements with standard solutions are necessary. The easy handling is a consequence of the possibility to apply samples and other solutions by usual laboratory equipment or by a pipetting o. automate.
Besides manual procedures, automated procedures are improved by application of the invented reaction vessel o i1. In such procedures, the application of the sample and the further steps of the procedure are performed by an automated sample processing device. Such a sample processing device is used for example in the online production process control of antibodies produced in a fermenter. In such procedures the samples are automatically applied in time intervals of about 6 to 8 hours, and the antibody concentration in the fermentation medium can be continuously determined rapidly and easily over a long time period using the disposable reaction vessel 1. A system for antibody production control using the invented disposable reaction vessel 1 is schematically described in fig. 2. Therein, the disposable reaction vessel 1 is included in the automated sample processing device.
staffleekaepspci/36316.93_ 2.5.96 5b The present procedure can be performed rapidly without application of high pressures to the disposable reaction vessel 1 after sample application. But low suction or pressure forces can be used for quicker performance, e.g. by centrifugation or pumping.
If necessary, several disposable reaction vessels 1 can be connected in series or parallel in the present procedure. This allows e.g. the simultaneous determination of several parameters in one single sample or the simultaneous analysis of several samples.
0 e* e a ao 00o go staff/ae/keep/spec/36316.93_1 2.5.96 6 The connection of several disposable reaction vessels in series is advantageous e.g. for the performance of allergy tests. Therein, a different antigen (allergen) is applied to each different column, then the columns are connected in series, and the sample containing the antibody of the class IgE which mediates the allergic reaction is applied to the first reaction vessel.
The sample flows successively through the different disposable reaction vessels 1 containing the different allergens. The IgE of the sample will be bound in the reaction vessel which contains the allergy-evoking antigen, and can be detected e.g. via fluorescence detection. In this way, one single sample can be tested simultaneously with many different potential allergens.
