Mouse B7-H2 Antibody

ICOS binding to Mouse B7-H2-transfected HEK293 Human Cell Line is Blocked by Mouse B7-H2 Antibody. In a functional flow cytometry test, Recombinant Mouse ICOS Fc Chimera (Catalog # 168-CS, 500 ng/mL) binds to HEK293 human embryonic kidney cell line transfected with recombinant mouse B7-H2 (black dotted line). Binding is completely blocked (orange histogram) by 0.5 µg/mL of Rat Anti-Mouse B7-H2 Monoclonal Antibody (Catalog # MAB10083). Rat IgG2A Isotype Control (Catalog # MAB006) at 0.5 µg/mL was used as a control (blue line). Ligand binding was detected by staining cells with Mouse Anti-Human IgG Fc APC-conjugated Monoclonal Antibody (Catalog # FAB110A).

Detection of Mouse B7-H2 in HEK293 Human Cell Line Transfected with Mouse B7-H2 and eGFP by Flow Cytometry. HEK293 human embryonic kidney cell line transfected with (A) mouse B7-H2 or (B) irrelevant transfectants and eGFP was stained with Rat Anti-Mouse B7-H2 Monoclonal Antibody (Catalog # MAB10083) followed by APC-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113). Quadrant markers were set based on control antibody staining (Catalog # MAB006). View our protocol for Staining Membrane-associated Proteins.

IL-4 Secretion Induced by B7-H2 and Neutralization by Mouse B7-H2 Antibody. Recombinant Mouse B7-H2 (Catalog # 8127-B7) induces IL-4 secretion in the D10.G4.1 mouse helper T cell line in the presence of Rat Anti-Mouse CD3 Monoclonal Antibody (Catalog # MAB4841) in a dose-dependent manner (orange line), as measured by the Mouse IL-4 Quantikine ELISA Kit (Catalog # M4000B). Under these conditions, IL-4 secretion elicited by B7-H2 (2.5 µg/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse B7-H2 Monoclonal Antibody (Catalog # MAB10083). The ND₅₀ is typically 0.3-1.8 µg/mL.
