Anti-TRIP-Br2 antibodies enable researchers to detect and measure the TRIP-Br2 antigen in biological samples. This target is a reported synonym of the SERTAD2 gene, which encodes SERTA domain containing 2. This protein is known to function in the regulation of cell growth, among other biological roles. The human version of TRIP-Br2 has a canonical amino acid length of 314 residues and a protein mass of 33.9 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include Sei-2 and TRIP-Br2.
