Anti-B7X antibodies enable researchers to detect and measure the B7X antigen in biological samples. This target is a reported synonym of the VTCN1 gene, which encodes V-set domain containing T cell activation inhibitor 1. This protein is known to function in adaptive immune responses and the regulation of apoptosis, among other biological roles. The human version of B7X has a canonical amino acid length of 282 residues and a protein mass of 30.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the bronchus and nasopharynx. B7X is a member of the BTN/MOG protein family. ELISA is a widely used application for the B7X antibodies listed below. In addition, Western Blot is also a common application.
