Anti-RB1 (phospho S795) Antibody

The product from Antibodies.com is a rabbit polyclonal IgG antibody that recognises Retinoblastoma protein (pRB) when phosphorylated at serine 795. This residue is a direct substrate of the Cyclin D–CDK4/6 complex, so detection of pRB S795 phosphorylation is widely used as a read-out of CDK4/6 pathway activity, G1/S checkpoint progression, and oncogenic signalling in cancer research. The reagent is supplied at 100 µl as an unconjugated primary antibody validated for Western blot on human samples, giving researchers flexibility to pair it with HRP, fluorophore, or other labelled secondary antibodies of their choice. Host species is rabbit, clonality is polyclonal, and reactivity is specific to human RB1, with selectivity directed toward the phosphorylated S795 form rather than the unmodified protein.
