p21 Waf1/Cip1 Antibodies

Santa Cruz Biotechnology delivers a wide array of p21 Waf1/Cip1 monoclonal antibodies for research in cell cycle regulation and tumor suppression. p21 Waf1/Cip1 monoclonal antibodies are compatible with multiple research applications, including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). p21 Waf1/Cip1 is a crucial cyclin-dependent kinase inhibitor that plays a significant role in regulating the cell cycle and maintaining genomic stability. By inhibiting cyclin-CDK complexes, p21 Waf1/Cip1 helps to control cell proliferation and is often upregulated in response to DNA damage, making it a key player in tumor suppression and cellular stress responses. Understanding the function of p21 Waf1/Cip1 is essential for elucidating mechanisms of cancer development and progression. Researchers can explore the complex interactions between p21 Waf1/Cip1 and other cell cycle regulators using specific monoclonal antibodies. Advanced research techniques with p21 Waf1/Cip1 monoclonal antibodies enable detailed analysis of protein expression patterns and cellular localization. Investigating p21 Waf1/Cip1's role in different cellular contexts can reveal new insights into cancer biology and potential therapeutic targets. Santa Cruz Biotechnology monoclonal antibodies for p21 Waf1/Cip1 support researchers worldwide in advancing our understanding of cell cycle regulation and cancer biology.
