Anti-sir2 antibodies enable researchers to detect and measure the sir2 antigen in biological samples. This target is a reported synonym of the SIRT2 gene, which encodes sirtuin 2. This protein is known to function in autophagy pathways and cell division, among other biological roles. The human version of sir2 has a canonical amino acid length of 389 residues and a protein mass of 43.2 kilodaltons, although 5 isoforms have been identified. It is reported to be notably expressed in many tissues, such as the smooth muscle and testis. This target antigen may also be known as SIR2L. Western Blot is the most common application for the sir2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
