Immunogen Human p21
Clone 6B6
Isotype IgG1
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.

Alternative Name p21
Background P21 belongs to a class of tumor suppressors including p16 and p27 which control progression through the cell cycle by inhibiting the activity of cyclin-cdk complexes. p21 is also known as senescent cell-derived inhibitor 1 (Sdi1), wild-type p53-activated fragment 1 (Waf1), Cdk-interacting protein 1 (Cip1), p21 and p53-regulated inhibitor of Cdks (Pic1). p21 mRNA is expressed at higher levels in senescent fibroblasts than in actively growing cells. When introduced into proliferating foreskin fibroblasts, p21 inhibits DNA synthesis and cell cycle arrest. p53 can activate p21 gene expression via a p53 binding site identified in the promoter of the p21 gene.
Molecular Weight 21 kDa
Research Area Cell Cycle
Application Notes Applications include immunoprecipitation (1-2 µg/1x10^6 cells), western blot analysis (1-2 µg/ml) and immunohistochemistry of paraformaldehyde-fixed cultured cells (0.5-2.5 µg/ml) and acetone-fixed, frozen and formalin-fixed paraffin-embedded (10 µg/ml) tissue sections. MCF7 human breast carcinoma cells (ATCC HTB-22) are suggested as a positive control. WI-38 human lung fibroblasts (ATCC CCL-75) treated with doxorubin (Adriamycin) can also be used as a positive control.
