p-Waf1/Cip1/CDKN1A p21 Antibody (D-6): sc-377569

p-p21 Waf1/Cip1 Antibody (D-6) is a mouse monoclonal IgG3 kappa light chain antibody that detects Thr 145 phosphorylated p21 Waf1/Cip1 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). anti-p21 Waf1/Cip1 antibody (D-6) is available in a non-conjugated form, allowing for versatile experimental design. p21 Waf1/Cip1 protein plays a crucial role in cell cycle regulation by acting as a potent inhibitor of cyclin-dependent kinases (Cdks), which are essential for the transition between different phases of the cell cycle. When phosphorylated at Thr 145, p21 retains its ability to bind to and inhibit cyclin-Cdk complexes, effectively preventing the phosphorylation of the retinoblastoma protein (Rb), a key step required for the transition from G1 phase to S phase. This inhibition halts cell cycle progression, enabling cells to repair damaged DNA, undergo senescence, or initiate apoptosis in response to stress or oncogenic signals. By coordinating these responses, p21 maintains genomic stability and prevents unchecked cell division. p21 Waf1/Cip1 expression is tightly regulated and induced by wild-type p53, reinforcing its role in tumor suppression. Understanding p21 Waf1/Cip1 phosphorylation dynamics provides critical insights into mechanisms controlling cell proliferation and their dysregulation in cancer. p21 Waf1/Cip1 monoclonal antibody (D-6) serves as an essential tool for exploring regulatory mechanisms of cell cycle arrest and impact of p21 phosphorylation on cellular responses to stress and DNA damage.
