Mouse p21 Recombinant monoclonal antibody, PBS Only (Detector)

• 

  WB analysis using 85435-2-RR (same clone as 85435-2-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 85435-2-RR (Cdkn1a antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 85435-2-PBS in a different storage buffer formulation.

  IF Staining of NIH/3T3 using 85435-2-RR (same clone as 85435-2-PBS)

  Immunofluorescent analysis of (4% PFA) fixed NIH/3T3 cells using Cdkn1a antibody (85435-2-RR, Clone: 242478H2 ) at dilution of 1:1000 and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2), CL594-Phalloidin (red). This data was developed using the same antibody clone with 85435-2-PBS in a different storage buffer formulation.

Background Information

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.
