Anti-RB1 (phospho S795) Antibody

A phospho-selective affinity reagent from Antibodies.com, this unconjugated rabbit polyclonal IgG reagent recognizes human retinoblastoma protein 1 (RB1) only when serine 795 is phosphorylated. The antibody is intended for western blot detection in cell lysates, where it supports investigations of CDK-associated G1/S checkpoint control, E2F pathway activity, and tumor suppressor signaling in cancer biology and proliferation research.

Supplied as a 200 µl liquid aliquot in a single vial, the reagent is unconjugated and can be paired with a laboratory-chosen HRP- or fluorophore-conjugated secondary antibody for chemiluminescent, chromogenic, or fluorescent western blot readout. As a polyclonal reagent, it offers recognition of multiple epitopes around the phospho-S795 site, which is useful when probing dynamic changes in RB1 phosphorylation across experimental conditions.

Intended for research use only and not for diagnostic or therapeutic purposes, the antibody is reactive with human samples. To preserve the phospho-epitope, lysates should be prepared promptly under conditions that maintain protein phosphorylation, and the vial should be aliquoted and stored refrigerated with protection from repeated freeze-thaw cycles, following the supplied protocol and lot-specific documentation.
