Product Specific Information
The H74 monoclonal antibody reacts with human B7-S1, also known as B7-H4 and B7x. Cross-reactivity to other proteins has not been determined. B7S1 is a newly discovered member of the B7 family and may regulate T cell costimulation depending on B cell activation status. BTLA is reported as a counter receptor, but further studies are needed to confirm the ligand for B7-H4.
H74 stains human B7-H4 transfected cells and not peripheral blood cells. The exact expression pattern of B7-H4 has not been fully characterized.
- Applications Reported: Flow cytometric analysis
- Applications Tested: Pre-titrated and tested on human B7-H4-transfected cells
- Recommended Usage: 5 µL (0.125 µg) per test (100 µL final volume, 10⁵–10⁸ cells/test)
- Excitation: 488–561 nm
- Emission: 578 nm
- Laser Compatibility: Blue, Green, Yellow-Green
- Filtration: 0.2 µm post-manufacturing filtered
Target Information
B7-H4 (B7x, VTCN1) is a costimulatory protein acting as a negative regulator of T-cell mediated immunity. Though its receptor is unknown, it delivers inhibitory signals to T-cells, preventing proliferation, cell cycle progression, and interleukin-2 production.
B7-H4 is expressed on activated T-cells, B-cells, monocytes, and dendritic cells. Aberrant expression is linked to lung, breast, and ovarian cancers. It is primarily membrane-bound on lymphoid cells and may help tumor cells evade immune responses.
VTCN1 is a potential biomarker for early detection of ovarian cancer and renal cell carcinoma (RCC).
