Description
VSIG8 Protein, Mouse (HEK293, His) is the recombinant mouse-derived VSIG8 protein, expressed by HEK293, with C-6*His labeled tag.
Background
V-set and immunoglobulin domain-containing protein 8 (VSIG8) is a membrane protein belonging to complement receptor of the immunoglobulin superfamily. VSIG8 has RNA binding activity and is a human T-cell co-inhibitory ligand. VSIG-8 inhibits the production of cytokines (IL-2, IFN-γ, IL-17, IL-6, and IL-19), chemokines (MCP-1, MCP-10, and IP-10) and other proteins (IGFBP3 and RBP4) on anti-CD3 activated human CD3 T cells. VSIG-8 significantly reduces the production of IFN-γand IL-2 on both CD4 and CD8 T cells in the presence of T-cell receptor signaling. VSIG-8 markedly suppresses anti-CD3-induced human T cell proliferation and profoundly decreases the conversion of naïve CD4+ T cells into Th1 cells[1][2].
Verified Bioactivity
Measured by its ability to chemoattract Jurkat human T-lymphocyte leukemia cells. The ED50 this effect is 0.7887 μg/ml, corresponding to a specific activity is 1267.91 units/mg.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, pH 7.4.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
