VISTA/B7-H5 Protein, Human (Biotinylated, HEK293, His-Avi)

Customer Review

Based on 1 Customer Validation

VISTA/B7-H5 protein, an immunoregulatory receptor, inhibits T-cell response and may regulate embryonic stem cell differentiation by inhibiting BMP4 signaling. It also stimulates MMP14-mediated MMP2 activation, suggesting a role in matrix metalloproteinase processes. These roles highlight the significance of VISTA/B7-H5 in immune regulation, embryonic development, and extracellular matrix dynamics. VISTA/B7-H5 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived VISTA/B7-H5 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.
