Anti-Rb Antibody

Produced by Antibodies.com, this primary antibody is an affinity-purified polyclonal reagent raised in rabbit against the retinoblastoma (Rb) protein, supplied as a 50 µl liquid aliquot at 1 mg/mL in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide. The unconjugated antibody is validated for use in Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF) and ELISA, and shows broad cross-reactivity across Human, Mouse and Rat samples, making it suitable for cell-cycle, tumour-suppressor and cancer-research workflows in both clinical and basic-science laboratories. Because the reagent is polyclonal, it recognises multiple epitopes on endogenous Rb (also known as RB1, pRb, p105-Rb, p110-RB1 or pp110), supporting robust signal in standard Western blot and IHC protocols. The antibody is shipped at 4 °C and should be aliquoted and stored at −20 °C upon receipt; repeated freeze/thaw cycles should be avoided to preserve activity. For research use only, this Antibodies.com reagent is offered through authorised regional distributors such as Abdulla Fouad for Medical Supplies & Services (AFMS) in Saudi Arabia, ensuring local technical support, logistics and quotations in SAR for institutional buyers.
