VSIG4 Protein, Human (HEK293, Fc)

VSIG4 Protein, a phagocytic receptor, robustly inhibits T-cell proliferation and IL2 production, serving as a potent alternative complement pathway convertase inhibitor. VSIG4 Protein, Human (HEK293, Fc) is the recombinant human-derived VSIG4 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of VSIG4 Protein, Human (HEK293, Fc) is 265 a.a., with molecular weight of ~75.0 kDa.

VSIG4 Protein serves as a phagocytic receptor and functions as a robust negative regulator of T-cell proliferation and IL2 production. Additionally, it acts as a potent inhibitor of the alternative complement pathway convertases.

Approximately 75.0 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<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. 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.
