Hintergrundinformationen

CDKN1A (p21, CIP1, WAF1) is a cyclin-dependent kinase inhibitor. CDKN1A binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at the G1 phase. The expression of CDKN1A is induced by wild-type but not mutant p53 protein, through which CDKN1A mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. CDKN1A can interact with proliferating cell nuclear antigen (PCNA), and plays a regulatory role in S phase DNA replication and DNA damage repair. CDKN1A was reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of CDK2, and may be instrumental in the execution of apoptosis following caspase activation. Two alternatively spliced variants, which encode an identical protein, have been reported.

Hadil (Verified Customer) (05-24-2023)

I prepared this antibody in odyssey blocker at 1:1000 and incubated at 4 C overnight and seemed to get a good signal for p21. There were some non-specific bands properly caused by long incubation periods. So, i would recommend using it at this concentration for 1.5-2 hr at RT.

• Applications: Western Blot
• Primary Antibody Dilution: 1:1000
• Cell Tissue Type: Mammalian cell lines

Malak (Verified Customer) (04-22-2021)

The best incubation period for this antibody is 1.5 hr at room temperature, longer incubations (especially overnight at 4°C) may result in aspecific bands.

• Applications: Western Blot
• Primary Antibody Dilution: 1/1000
• Cell Tissue Type: Hepatic cancer cell extract
