Anti-B7H4 antibodies are protein reagents that detect specific antigens. The B7H4 antigen is another term for the human protein V-set domain containing T cell activation inhibitor 1, encoded by the VTCN1 gene. The protein is known to function in adaptive immune responses and the regulation of apoptosis, among other biological roles. Canonically, it has an amino acid length of 282 residues and a mass of 30.9 kilodaltons. Its subcellular localization is in the cell membrane and it is notably expressed in breast, ovarian, endometrial, renal cell (RCC) and non-small-cell lung cancers (NSCLC). The B7H4 protein is a member of the BTN/MOG protein family. ELISA is a widely used application for the B7H4 antibodies listed below. In addition, Western Blot is also a common application.
