Specificity
Clone 5G7 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects p21/Waf1/Cip1 protein.
His-tagged full-length recombinant human Cyclin-dependent kinase inhibitor 1 (p21).
Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected p21 in HUVEC and NIH 3T3 cells.
Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected p21 in human cervical cancer tissue sections.
Note: Actual optimal working dilutions must be determined by the end user as specimens and experimental conditions may vary.
Anti-p21, clone 5G7 ZooMAb , Cat. No. ZRB1141, is a recombinant rabbit monoclonal antibody that specifically targets p21-Waf1-Cip1 and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Target description
Cyclin-dependent kinase inhibitor 1 (UniProt: P38936; also known as CDK-interacting protein 1, Melanoma differentiation-associated protein 6, MDA-6, p21) is encoded by the CDKN1A (also known as CAP20, CDKN1, CIP1, MDA6, PIC1, SDI1, WAF1) gene (Gene ID:1026) in human. p21 belongs to the Cip and Kip family of CDK inhibitors. It binds to and inhibits cyclin-dependent kinase activity, preventing phosphorylation of critical cyclin-dependent kinase substrates and blocking cell cycle progression. It binds tightly to the G1 and S phase kinases, cyclin E/Cdk2, cyclin D/Cdk4, and cyclin A/Cdk2, and effectively inhibits their activity. However, its effects on G2/M kinases is minimal. It binds the cyclin subunit through a conserved Cy1 motif in the N-terminal half and through a weaker and Cy2 motif in the C-terminal half. p21 also inhibits proliferating cell nuclear antigen (PCNA) and binds to and blocks the inactivation of retinoblastoma protein (Rb), which is essential for cell cycle progression. It is an important effector of p53 and is important in the DNA-damage checkpoint. It is expressed in all adult tissues, with 5-fold lower levels observed in the brain. Is cyclin binding site is localized to amino acids 17-24 and CDK binding occurs in the region of 53-58 residues. p21 is shown to suppress tumor growth by promoting cell cycle arrest in response to various stimuli. However, it is often misregulated in various human cancers. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
