Anti-BARR2 antibodies enable researchers to detect and measure the BARR2 antigen in biological samples. This target is a reported synonym of the ARRB2 gene, which encodes arrestin beta 2. This protein is known to function in brain development and the regulation of apoptosis, among other biological roles. The human version of BARR2 has a canonical amino acid length of 409 residues and a protein mass of 46.1 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, cytoplasmic vesicles, and cytoplasm of cells. Other names for this target antigen include ARB2, ARB2, and ARR2. Western Blot is the most common application for the BARR2 antibodies listed below. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
