Binding of proteins, including pp60src, to activated CH-sepharose 4B
Mol Biol Rep.
1987.
Abstract
Activated CH-Sepharose 4B and protein A Sepharose CL-4B can bind, selectively and non-specifically, polypeptides from chick embryo cells. The major polypeptides bound have apparent molecular masses of 57-60 kDa and 47-49 kDa and cannot be eluted by extensive washing with buffers containing detergents. One of the 57-60 kDa polypeptides was identified by immunoblotting as the transforming protein of Rous Sarcoma Virus (RSV), pp60src. This polypeptide could be removed from the solid phase immunoabsorbent with 60% dimethylsulfoxide, but not with 2% SDS, 5% beta-mercaptoethanol, 1 M NaCl or 0.1% Tween 20.
