Active Recombinant Rhesus macaque VTCN1 Protein, His-tagged

• Cat.No.: VTCN1-1519R
• Product Overview: Recombinant Rhesus macaque B7-H4/VTCN1 Protein (Phe29-Ala258) with a C-His tag was expressed in human cells.

Specification

• Description: B7 Homolog 4 (B7-H4) is glycosylated member of the B7 family of immune costimulatory proteins.It is widely expressed, including in kidney, liver, lung, pancreas, placenta, prostate, spleen, testis and thymus. B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. It also involved in promoting epithelial cell transformation.
