B7-H6 Antibody (1018415) [Unconjugated]

In a functional ELISA, 20-120 ng/mL of Mouse Anti-Human B7-H6 Monoclonal Antibody (Catalog # MAB71445) will block 30% of the binding of 20 ng/mL of Recombinant Human NKp30 Fc Chimera Protein (1849-NK) to immobilized Recombinant Human B7-H6 His-tag Protein (9309-B7) coated at 1 μg/mL (100 µL/well). At 1 μg/mL, this antibody will block >50% of the binding.

Background

B7-H6 is a glycosylated member of the B7 family of immune co-stimulatory proteins (1  2). Mature human B7-H6 consists of a 238 amino acid (aa) extracellular domain (ECD) that contains one Ig-like V domain and one Ig-like C1 domain, a 21 aa transmembrane segment, and a 171 aa cytoplasmic domain that contains one ITIM, one SH2, and one SH3 motif (3). Both of the Ig-like domains carry N-linked glycosylation (4). Within the ECD, human B7-H6 shares 99%, 94%, and 87% aa sequence identity with chimpanzee, orangutan, and gibbon B7-H6, respectively, and 53%-56% with bovine, canine, and equine B7-H6. Orthologs in mouse and rat have not been identified. The Ig-like V domain mediates 1:1 stoichiometric binding of B7-H6 to NKp30 expressed on NK cells (4, 5). It does not show binding to NKp44, NKp46, or NKG2D (3, 6). Ligation of NKp30 by B7-H6 induces NK cell activation and target cell cytolysis (3). B7-H6 is expressed on a wide range of hematopoietic, carcinoma, and melanoma tumor cells, which is consistent with the detection of NKp30 binding sites on many tumors (3, 7). The expression of NKp30 ligands on tumor cells correlates with tumor cell sensitivity to NKp30‑dependent cell lysis (7).
