Handling Advice: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.

Storage: 4 °C/-20 °C/-80 °C

Storage Comment: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Target Details

Target: VSIG4 (V-Set and Immunoglobulin Domain-Containing Protein 4 (VSIG4))

Alternative Name: V-Set and Immunoglobulin Domain-Containing Protein 4/VSIG4

Background: Recombinant Human V-Set and Immunoglobulin Domain-Containing Protein 4/VSIG4 produced by transfected human cells is a secreted protein with sequence (Arg20-Val284) of Human VSIG4 fused with a FC tag at the C-terminus.
V-set and immunoglobulin domain-containing protein 4(VSIG4) is a transmembrane protein contains a signal peptide, a V-type Ig-like domain, a C2-type Ig-like domain, several potential O-glycosylation sites, and an intracellular domain with 2 potential phosphorylation sites and is structurally related to the B7 family of immune regulatory proteins. This protein is also a receptor for the complement component 3 fragments C3b and iC3b.The main function is strong negative regulator of T-cell proliferation and IL2 production and it is also potent inhibitor of the alternative complement pathway convertases. It abundantly expressed in several fetal tissues such as adult tissues, highest expression in lung and placenta and it also expressed in resting macrophages.
