Background Information
CDKN1B, also named as P27 or KIP1, is a cyclin-dependent kinase inhibitor, which shares a limited similarity with CDK inhibitor CDKN1A/p21. P27 binds to and prevents the activation of cyclin E-CDK2 or cyclin D-CDK4 complexes, and thus controlling cell cycle progression at G1. The degradation of this protein, which is triggered by its CDK dependent phosphorylation and subsequent ubiquitination by SCF complexes, is required for the cellular transition from quiescence to the proliferative state. Downregulation of P27 has been implicated in the progression of several malignancies, including lung cancer, hepatocellular carcinoma, salivary cancer, oral squamous cell carcinomas, and gastric cancer.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Malak (Verified Customer) (04-22-2021) | The optimal incubation period is 1.5 hr at room temperature. Avoid incubating the antibody overnight as it may result in aspecific signals.
|
FH Susmita (Verified Customer) (09-17-2020) | Antibody is working very good for WB
|
FH Joshua (Verified Customer) (07-27-2019) | Cells fixed in 4% paraformaldehyde and stained at 4C overnight. Decent staining with some background in rabbit cells. Nuclear localization as expected.
