Separation of SO-Rb_ (50)cells antigen corresponding to the monoclonal antibody of anti-retinoblastoma / 中华眼底病杂志

ABSTRACT

Objective To separate the SO-Rb 50cells antigen corresponding to the monoclonal antibody of anti-retinoblastoma. Methods The antigen corresponding to the monoclonal antibody of anti-retinoblastoma was separated elementarily by ion-exchange chromatography, and was identified by dot-blotting using the monoclonal antibody of anti-retinoblastoma. The target protein band of the antigen was separated in light of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Results A special unmixed band of SO-Rb 50cells antigen was separated with the relative molecular weight of 83?103. Conclusion The antigen corresponding to the monoclonal antibody of anti-retinoblastoma could be separated from SO-Rb 50cells.
