Anti-TB2 antibodies enable researchers to detect and measure the TB2 antigen in biological samples. This target is a reported synonym of the REEP5 gene, which encodes receptor accessory protein 5. This protein is known to play an important role in heart function and development by regulating the organization and function of the sarcoplasmic reticulum in cardiomyocytes. The human version of TB2 has a canonical amino acid length of 189 residues and a protein mass of 21.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the ER of cells and widely expressed in many tissue types. Other names for this target antigen include C5orf18, D5S346, and DP1. Indicated applications for TB2 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
