Web5-bromo-4-chloro-3-indolyl phosphate (BCIP) has a molecular weight of 433.6, and hydrolysis by alkaline phosphatase (AP) results in a blue-purple precipitate that can be deposited on nitrocellulose or nylon membranes. BCIP can be used as a chromogenic substrate for both immunoblotting and immunohistochemical studies. WebThe hydrolysis of glucose 6-phosphate begins with a nucleophilic attack on the sugar-bound phosphate by His176 resulting in the formation of a phosphohistidine bond and the degradation of a carbonyl. A Negatively charged oxygen then transfers its electrons reforming a carbonyl and breaking its bond with glucose. WebPhosphorylation reactions, driven by competing kinases and phosphatases, are central elements of cellular signal transduction.
