SR protein from a cellular source oxidizes to dimers and other multimers. Total cellular protein was prepared from three cultures of mouse primary astrocytes and resolved by 10% SDS-PAGE in the absence (A) or presence (B) of 2.5% β-mercaptoethanol in the sample buffer. SR protein (arrow) was detected by western blot with anti-SR antibody. Lane 1 contained molecular weight standards (kDa).
