Recombinant Human RB1/OSRC Protein (rp231386) - SDS-PAGE
3 μg/lane of Recombinant Human RB1/OSRC Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 18.1 & 72.9 kDa under reducing conditions and 18.6 & 36.5 & 74.2 & 93.9 kDa under non-reducing conditions.
The C-terminal domain of pRB has a propensity for self-association, which facilitates the formation of pRB oligomers/multimers (Uniprot: P06400).
