Listed are ELISA Kits for the detection of B7H4, an alias name of V-set domain containing T cell activation inhibitor 1. The human protein, encoded by the gene VTCN1, is 282 amino acid residues long and has a mass of 30,878 daltons. However, there are up to 4 reported isoforms. It is a member of the Immunoglobulin superfamily, BTN/MOG family. This protein is reported to have a membrane cellular localization, and is glycosylated. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, and rat. This target may also be known as: B7 family member H4, B7 homolog 4, B7 superfamily member 1, T cell costimulatory molecule B7x, B7-H4, B7H4, and B7S1.
