Anti-p15 INK4b antibodies enable researchers to detect and measure the p15 INK4b antigen in biological samples. This target is a reported synonym of the CDKN2B gene, which encodes cyclin dependent kinase inhibitor 2B. This protein is known to function in pathways of aging and the cell cycle, among other biological roles. The human version of p15 INK4b has a canonical amino acid length of 138 residues and a protein mass of 14.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include CDK4I, INK4B, and MTS2. Immunohistochemistry is a widely used application for the p15 INK4b antibodies listed below. In addition, Western Blot is also a common application.
