title: [Patterns in the immunoenzyme analysis of bacterial cells].
abstract: Some regularities of the enzyme immunoassay (EIA) of whole bacterial cells have been studied on one of the bacillary species of contaminant microflora. Early detection of this microorganism is highly important for the microbiological production of alpha-amylase and alkaline protease (produced by Bacillus subtilis). The effective kinetic and equilibrant parameters of the interaction of peroxidase-labeled antibodies with the cells of the contaminant microflora in the solution and on the surface of the polystyrene plates have been defined. Two methods for the separation of cells after their interaction with peroxidase-labeled antibodies have been optimized: filtration involving the use of special filter plates and centrifugation in plates. The method for the immobilization of cells in the wells of standard assay plates by centrifugation has been proposed. Four EIA methods for measurement of contaminant microflora have been developed and optimized. These methods permit the determination of the microflora at concentration of 5 X 10(5)-5 X 10(4) cells/ml, depending on the scheme of the assay, within 1-3.5 minutes.
