Anti-TROP2 antibodies enable researchers to detect and measure the TROP2 antigen in biological samples. This target is a reported synonym of the TACSTD2 gene, which encodes tumor associated calcium signal transducer 2. This protein is known to function in stem cell differentiation, among other biological roles. The human version of TROP2 has a canonical amino acid length of 323 residues and a protein mass of 35.7 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in many tissues, such as the cervix, urinary bladder, and bronchus. Other names for this target antigen include EGP-1, EGP1, and GA733-1. Western Blot is a widely used application for the TROP2 antibodies listed below. In addition, ELISA is also a common application.
