| Brain ligatin : a membrane lectin that binds acetylcholinesterase . ^^^ From membrane preparations of cerebrum , this procedure solubilized ligatin and a membrane bound acetylcholinesterase ( EC 3 . 1 . 1 . 7 ) . ^^^ Binding of the cosolubilized acetylcholinesterase to ligatin could be demonstrated in vivo by affinity chromatography using the immobilized lectin . ^^^ These sugars were also effective in eluting bound brain acetylcholinesterase from ligatin affinity columns . ^^^ |
