The Recombinant CDKN2A/p16INK4a Monoclonal Antibody is a recombinant rabbit monoclonal antibody (clone C321612) against CDKN2A/p16INK4a. Members of the INK4 family of cyclin dependent kinase inhibitors include p16 INK4A, p15 INK4B, p18 INK4C, and p19 INK4D. The INK4 family members inhibit cyclin dependent kinases 4 and 6 (CDK4 and CDK6), causing cell cycle arrest in G1 phase. The INK4A-ARF-INK4B locus on chromosome 9p21, frequently lost in human cancer, encodes the INK4 family members p16 INK5A and p15 INK4B, as well as the unrelated protein, ARF.p16 INK4A expression, typically repressed in the absence of stress, is thought to drive cells into senescence, and p16 INK4A expression is a commonly used marker of senescent cells. p16 INK4A protein expression is often altered in human cancer, and high expression is currently used as a predictive biomarker in cervical cancer. Produced by recombinant technology in Rabbit hosts and purified by Protein A affinity chromatography, this Rabbit IgG antibody is reactive against Human samples.
This antibody is suitable for WB and IHC applications. It has been validated by WB analysis of MCF-7 (Negative control), HeLa, HEK-293 and IHC analysis of Human cervical cancer. The target is localized to the cytoplasm, nucleus.
