Anti-RB1 Antibody

This primary antibody from Antibodies.com targets the retinoblastoma protein (RB1), a ~110 kDa tumor suppressor that controls the G1/S checkpoint by sequestering E2F transcription factors. The polyclonal rabbit IgG reagent is supplied at 100 µL as an unconjugated vial suitable for western blot detection of mouse-derived samples, where it binds the endogenous retinoblastoma protein.

Researchers investigating cell cycle regulation, cancer biology, and tumor suppressor function can use this reagent to examine RB1 expression and phosphorylation status across mouse cell lysates and tissue homogenates. The rabbit host and polyclonal clonality broaden epitope coverage, while the unconjugated format offers flexibility for downstream secondary antibody selection and tailored detection chemistry in standard immunoblotting workflows.
