Direct cytotoxicity of ethylcholine mustard aziridinium in cerebral microvascular endothelial cells.

abstract：:Antisera were raised in rabbits against the alpha subunit of a GTP-binding protein, Go. Because the antisera cross-reacted weakly with the alpha subunit of inhibitory GTP-binding protein of adenylate cyclase (Gi), they were purified with a Go alpha-coupled Sepharose column. Purified antibodies reacted only with Go alp...
