Abstract: The invention concerns a test element for carrying out an immunological sandwich test for determining an analyte from a liquid sample containing a reagent zone or conjugate zone which contains a conjugate of an analyte binding partner and a label which can be detected directly or indirectly by visual, optical or electrochemical means (e.g. an enzyme, fluorescent or direct label etc.) wherein said conjugate can be dissolved by the liquid sample, a detection zone which contains a permanently immobilized (i.e. which cannot be detached by the liquid sample) binding partner for the analyte or for complexes containing the analyte; and a control zone which contains a permanently immobilized binding partner for the conjugate of analyte binding partner and label characterized in that the control zone additionally contains one or more permanently immobilized binding partner(s) for the analyte or for complexes containing the analyte.

Abstract: A problem to be solved by the present invention is to provide an immunochromatographic test strip and a detection method using immunochromatography avoiding aggregation of colloidal gold conjugates while red blood cells in whole blood are agglutinated and then separated and removed in the case of using polybrene as a blood-agglutinating agent and the colloidal gold conjugates as a detection reagent. To solve the problem, the present inventers reviewed a past reagent configuration itself from a completely different viewpoint rather than selecting type and amount of polyanions and, as a result of extensive study on each element, the inventers surprisingly found that aggregation of colloidal gold can be suppressed by using a certain buffer solution without using neutralization by polyanions.

Abstract: A problem of the present invention is to provide an immunochromatographic test strip avoiding agglutination of colloidal gold while red blood cells in whole blood are agglutinated and then separated and removed in the case of using polybrene as a hemagglutinating agent and the colloidal gold conjugates as a detection reagent, and to provide immunochromatography using the test strip. To solve the problem, the present inventors reviewed the composition of the existing reagent itself from a completely different viewpoint rather than the selection of type or amount of polyanions, and as a result of extensive study on each element, the inventors surprisingly found that agglutination of colloidal gold may be suppressed by using a particular additive without neutralization by polyanions.

Abstract: Biological activity in holding pens in a micro-fluidic device can be assayed by placing in the holding pens capture objects that bind a particular material of interest produced by the biological activity. The biological material of interest that binds to each capture object can then be assessed, either in the micro-fluidic device or after exporting the capture object from the micro-fluidic device. The assessment can be utilized to characterize the biological activity in each holding pen. The biological activity can be production of the biological material of interest. Thus, the biological activity can correspond to or arise from one or more biological cells. Biological cells within a holding pen can be clonal cell colonies. The biological activity of each clonal cell colony can be assayed while maintaining the clonal status of each colony.

The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.
