Recombinant Human B7-H4 Protein, ≥95% (SDS-PAGE)

Cat. No.: rp167793
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. Azide Free ? Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory. His Tag ? His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. ≥95%(SDS-PAGE)

Overview

Purity
≥95% SDS-PAGE.
Endotoxin level
<0.1 EU/µg
Function
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. Involved in promoting epithelial cell transformation.
