| Description : |
V-set and immunoglobulin domain-containing protein 4 (VSIG4) is also known as Protein Z39Ig, is a type I transmembrane glycoprotein. VSIG4 is a B7 family-related protein and an Ig superfamily member. VSIG4 contains two Ig-like (immunoglobulin-like) domains. VSIG4 is abundantly expressed in several fetal tissues. In adult tissues, the highest expression of VSIG4 is in lung and placenta. VSIG4 functions as a negative regulator of T cell activation, and may be involved in the maintenance of peripheral T cell tolerance, and is also identified as a potent suppressor of established inflammation. VSIG4 is a phagocytic receptor, strong negative regulator of T-cell proliferation and IL2 production. |
| Form : |
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant. |
| Specificity : |
Protein Ratio: Passed as determined by the HABA assay/binding ELISA. |
| Molecular Mass : |
The protein has a calculated MW of 32.8 kDa. The protein migrates as 43-50 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation. |
| Purity : |
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS. |
| Storage : |
This product is stable after storage at: -20 to -70 centigrade for 12 months in lyophilized state; -70 centigrade for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower. Please avoid repeated freeze-thaw cycles. |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents. |
