Anti-ARF antibodies enable researchers to detect and measure the ARF antigen in biological samples. This target is a reported synonym of the CDKN2A gene, which encodes cyclin dependent kinase inhibitor 2A. This protein is known to function in the cell cycle and the regulation of cell growth, among other biological roles. The human version of ARF has a canonical amino acid length of 156 residues and a protein mass of 16.5 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. This target antigen may also be known as CDK4I. Western Blot is the most common application for the ARF antibodies listed below. ELISA and Immunohistochemistry are also common applications.
