Anti-ATP2B antibodies enable researchers to detect and measure the ATP2B antigen in biological samples. This target is a reported synonym of the ATP2A2 gene, which encodes ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 2. This protein is known to function in cell adhesion and the response to oxidative stress, among other biological roles. The human version of ATP2B has a canonical amino acid length of 1042 residues and a protein mass of 114.8 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the ER of cells and notably expressed in the heart muscle, cerebral cortex, cerebellum, caudate, and bronchus. This target antigen may also be known as DAR. Western Blot is the most common application for the ATP2B antibodies listed below. ELISA and Immunohistochemistry are also common applications.
