Anti-Tcrb antibodies enable researchers to detect and measure the Tcrb antigen in biological samples. This target is a reported synonym of the TRB gene, which encodes T cell receptor beta locus. This protein is known to function in adaptive immune responses, among other biological roles. The human version of Tcrb has a canonical amino acid length of 310 residues and a protein mass of 34.8 kilodaltons. It is reported to be localized in the cell membrane of cells.
