A number of ELISA Kits are available that target GI24, an alias of the protein, V-set immunoregulatory receptor. The human protein is encoded by the gene VSIR. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: B7-H5, B7H5, C10orf54, DD1alpha, Dies1, GI24, PD-1H, PP2135, SISP1, VISTA. Homology is conserved in other species, such as Mouse, Rat, Frog, Chicken.
