Anti-Rb (P789) Antibody

Raised in rabbit, this polyclonal IgG reagent from Antibodies.com binds the retinoblastoma tumor suppressor protein (Rb) at the P789 epitope. It is supplied as a 100 µl liquid aliquot at 1 mg/ml in phosphate buffered saline containing 0.05% sodium azide (approximate pH 7.2), unconjugated and ready for use in Western blot workflows. Validation work has shown reactivity with human, mouse, and rat samples, supporting cell-cycle and tumor suppressor studies, Rb pathway analysis, and related signaling investigations in cancer research. Researchers aliquot the antibody upon first use and store it refrigerated, handling it as a frozen-thaw-sensitive reagent and protecting it from light to preserve activity for downstream immunoblotting applications.
