p27/Kip1 was detected in immersion fixed paraffin-embedded sections of human prostate cancer tissue using 25 µg/mL Rat Anti-Human/Mouse/Rat p27/Kip1 Monoclonal Antibody (Catalog # MAB22561) overnight at 4 °C. Tissue was stained with the Human p27 Immunohistochemistry Detection Kit (brown; Catalog # CTS2256) and counterstained with hematoxylin (blue).

The cyclin-dependent kinase (cdk) inhibitor p27/Kip1 is a tumor suppressor protein that acts in the nucleus to enforce cell cycle checkpoints. p27/Kip1 binds to and inhibits many cyclin/cdk complexes, including cyclin D/cdk4, cyclin E/cdk2, and cyclin A/cdk2. This inhibition can subsequently block progression through different phases of the cell cycle. Human p27/Kip1 shares 88% and 87% amino acid sequence identity with mouse and rat p27/Kip1, respectively, while mouse and rat p27/Kip1 share 96% amino acid sequence identity.
