Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human p27 Kip1.

Background

p27 Kip1 is a member of the Cip/Kip family of cyclin-dependent kinase inhibitors. Like its relatives, p57 Kip2 and p21 Waf1/Cip1, the ability to enforce the G1 restriction point is derived from its inhibitory binding to CDK2/cyclin E and other CDK/cyclin complexes. Expression levels of p27 are upregulated in quiescent cells and in cells treated with cAMP or other negative cell cycle regulators. Downregulation of p27 can be induced by treatment with interleukin-2 or other mitogens; this involves phosphorylation of p27 and its degradation by the ubiquitin-proteasome pathway (1-4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western Blotting Image 1: p27 Kip1 (D69C12) XP® Rabbit mAb Expand Image
Western blot analysis from control HeLa cells (lane 1) or p27 Kip1 knockout HeLa cells (lane 2) using p27 Kip1 (D69C12) XP Rabbit mAb #3686 (upper) or B-Actin (D6A8) Rabbit mAb #8457 (lower). The absence of signal in the p27 Kip1 knockout HeLa cells confirms specificity of the antibody for p27 Kip1.
