Product Specific Information
In direct ELISAs and Western blots, less than 1% cross-reactivity with recombinant mouse B7-1, B7-2, B7-H1, B7-H2, B7-H3, and PD-L2 is observed.
Reconstitute at 0.2 mg/mL in sterile PBS.
Target Information
B7-H4 (also known as B7x, VTCN1) is a costimulatory protein functioning as a negative regulator of T-cell mediated immunity. 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 associated with lung, breast, and ovarian cancers.
Overexpression of B7-H4 may help tumor cells suppress T-cell immunity, facilitating tumor progression. VTCN1 may serve as a biomarker for early detection of ovarian cancer and renal cell carcinoma (RCC).
