Genetic transfer of endothelin converting enzyme activity to CHO-K1 cells: detection of positive cells by reverse hemolytic plaque assay.

We have established a novel method of molecular cloning of endothelin converting enzyme, a key enzyme in the production of a potent vasoconstrictor endothelin-1, by modification of the reverse hemolytic plaque assay. Also, we demonstrated that a cell line, CHO-K1, showed no detectable activity of endothelin converting enzyme. This cell line was transfected with a cDNA library of bovine endothelial cells. The modified reverse hemolytic plaque assay was shown to detect even a single CHO-K1 cell that was changed to produce mature ET-1 by transfection. Thus, this novel method is suggested to be useful for the molecular cloning of other secreted antigens and their processing enzyme.[1]
