Name: p21/Waf-1 Monoclonal Antibody clone CP74
Description and aplications: p21WAF1/Cip1/Sdi1/Pic1 is a tumor suppressor protein. Expression of p21WAF1 is induced by wild type, but not mutant, p53 suppressor protein. The p21WAF1 protein binds to cyclin/CDK complexes and inhibits their kinase activity thereby stopping cell cycle progression. It also binds to PCNA (proliferating cell nuclear antigen) and blocks DNA replication but not the DNA repair process.
Composition: anti-human p21 mouse monoclonal antibody purified from ascites. Prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide
Intended use : Immunohistochemistry (IHC) on paraffin embedded tissues. Not tested on frozen tissues or Western-Blotting
