Human B7‑H6 ELISA Standard Curve.

Recombinant Human B7-H6 protein was serially diluted 2-fold and captured by Mouse Anti-Human B7-H6 Monoclonal Antibody (Catalog # MAB7144) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human B7-H6 Monoclonal Antibody (Catalog # MAB71442) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Applications for Human B7-H6 Antibody

Application

Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human B7‑H6 Monoclonal Antibody (Catalog # MAB7144).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human B7-H6 DuoSet ELISA (Catalog # DY7144-05) for convenient development of a sandwich ELISA.

Background: B7-H6

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).
