Use of benzyldimethyl-n-hexadecylammonium chloride (cas 1602-97-7) (“16-BAC”), a cationic detergent, in an acidic polyacrylamide gel electrophoresis system to detect base labile protein methylation in intact cells

Add time:07/21/2019    Source:sciencedirect.com

A discontinuous polyacrylamide gel system operating at pH 4.0–1.5 which resolves proteins bearing base labile groups extracted from intact cells is described. It uses potassium phosphate buffer in the running and stacking gel and glycine as the trailing ion component. Proteins are solubilized with urea and benzyldimethyl-n-hexadecylammonium chloride, a cationic detergent. The utility of the system is illustrated by fluorographs of the pattern of protein methylation in blood platelets and the HL60 promyelocyte cell line.
