title: [Preparation and use of monoclonal antibodies against seal alkaline phosphatase].
abstract: Monoclonal antibodies (termed as APP.1 and related to subclass IgG1) against seal alkaline phosphatase, have been obtained. APP.1 did not influence the enzymatic activity of alkaline phosphatase. The dissociation constant for the APP.1 interaction with Greenland seal alkaline phosphatase was equal to 8.5 x 10(-10) M. It was found that APP.1 interact with intestinal isoenzymes of common and fur seal, calf and deer alkaline phosphatases. An APP.1 complex with seal alkaline phosphatase was obtained and successfully applied in immunoenzymatic analysis. The use of this complex made it possible to diminish the limit of detectability of antibodies against peptide fragments of HIV-1 and HIV-2 proteins. Moreover, this complex allowed the identification of cytokeratin-8 and vimentin in human kidney slices and embryonic fibroblast-like cells, respectively.
