This antibody p21Cip1 (pThr145) detects endogenous levels of p21Cip1 only when phosphorylated at Threonine 145.
纯化方法
Immunoaffinity Chromatography: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
免疫原
The antiserum was produced against synthesized phosphopeptide derived from human p21Cip1 around the phosphorylation site of threonine 145 (R-Q-TP-S-M).
Cell cycle progression is regulated by cyclins and their cognate Cdks. p21 (WAF1/CIP1) inhibits the activity of each member of the cyclin/Cdk family, and overexpression of this protein inhibits the proliferation of mammalian cells. The expression of p21 is inducible by a wide range of stress stimuli. p21 is tightly regulated at the transcriptional level by p53, and probably serves as the effector of p53 cell cycle control.Synonyms: CAP20, CDK-interacting protein 1, CDKN1, CIP1, Cyclin-dependent kinase inhibitor 1, MDA-6, MDA6, Melanoma differentiation-associated protein 6, PIC1, SDI1, WAF1
