Western Blotting

Western blot analysis of extracts from various cell types using p21 Waf1/Cip1 (12D1) Rabbit mAb.
Western Blotting

Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Fluorescein Conjugate) #6201 (-) or SignalSilence® p21 Waf1/Cip1 siRNA II (+), using p21 Waf1/Cip1 (12D1) Rabbit mAb #2947 and α-Tubulin (11H10) Rabbit mAb #2125. The p21 Waf1/Cip1 (12D1) Rabbit mAb confirms silencing of p21 Waf1/Cip1 expression and α-Tubulin (11H10) Rabbit mAb is used to control for loading and specificity of p21 Waf1/Cip1 siRNA.
IP

Immunoprecipitation of p21 from human umbillical vein endothelial cells (HUVECs) using p21 Waf1/Cip1 (12D1) Rabbit mAb. Western blot detection was performed using the same antibody.
IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human breast carcinoma using p21 Waf1/Cip1 (12D1) Rabbit mAb in the presence of control peptide (left) or antigen-specific peptide (right).
IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded HeLa cells, transfected with SignalSilence® Control siRNA (Unconjugated) #6568 (left) or SignalSilence® p21 Waf1/Cip1 siRNA II #6558 (right), using p21 Waf1/Cip1 (12D1) Rabbit mAb.
Flow Cytometry

Flow cytometric analysis of HeLa cells (red) and MCF7 cells (blue), using p21 Waf1/Cip1 (12D1) Rabbit mAb.

The tumor suppressor protein p21 Waf1/Cip1 acts as an inhibitor of cell cycle progression. It functions in stoichiometric relationships forming heterotrimeric complexes with cyclins and cyclin-dependent kinases. In association with CDK2 complexes, it serves to inhibit kinase activity and block progression through G1/S (1). However, p21 may also enhance assembly and activity in complexes of CDK4 or CDK6 and cyclin D (2). The carboxy-terminal region of p21 is sufficient to bind and inhibit PCNA, a subunit of DNA polymerase, and may coordinate DNA replication with cell cycle progression (3). Upon UV damage or during cell cycle stages when cdc2/cyclin B or CDK2/cyclin A is active, p53 is phosphorylated and upregulates p21 transcription via a p53-responsive element (4). Protein levels of p21 are downregulated through ubiquitination and proteasomal degradation (5).
