摘要：

A 96-well microtiter enzyme-linked immunosorbent assay was developed to assay the activity of the cytoplasmic domain of trkA tyrosine kinase. The assay involves immobilization of phospholipase C-gamma/glutathione S-transferase fusion protein on a microtiter plate, addition of the kinase reaction mixture, and detection by an antibody to phosphotyrosine followed by an alkaline phosphatase-conjugated second antibody. The substrate used in this system, phospholipase C-gamma, is one of several biologically important substrates for the phosphorylation reaction of receptor-linked tyrosine kinases. The assay was then used to characterize kinase inhibitory activities of various small molecules including analogs of K-252a. (C) 1996 Academic Press, Inc.
