產品提供形式：

Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

1. Soluble VSIG4 levels are associated with the progression and recurrence of ovarian cancer, indicating that soluble VSIG4 may be used as a potential biomarker for predicting tumor prognosis. PMID: 28498255
2. VSIG4 signaling provides an anti-immune evasion mechanism that prevents the outgrowth of intracellular bacteria in macrophages PMID: 27440002
3. The VSIG4 upregulation by LMP1 was regulated at the transcriptional level via the NF-kB signaling axis. PMID: 28859984
4. VSIG4 expression is significantly upregulated in human masticatory mucosa during wound healing PMID: 28005267
5. we concluded that let-7g-5p inhibits epithelial-mesenchymal transition (EMT) consistent with reduction of glioma stem cell (GSC) phenotypes by targeting VSIG4 in glioblastoma. PMID: 27634309
6. Data indicate that rotein kinase calpha (PKCalpha) plays a role in downregulating complement receptor Ig (CRIg coded by V-set and Ig domain-containing protein 4 VSIG4) expression. PMID: 25687755
7. complement receptor of the immunoglobulin superfamily-L-factor H protects glomerular mesangial cells from complement-mediated injury and proliferative lesions PMID: 25114177

11. These results suggest that T cells can opposite T cell hyporesponsiveness through dampening Z39Ig inhibitory signals from macrophages and thus maintain their anti-viral function in chronic hepatitis B. PMID: 20399148
12. hVSIG4 recombinant adenovirus-transfected DCs suppress T cell proliferation, cytokine production and activation marker expression with PMID: 19914289

14. These data indicate that the macrophage Z39Ig is involved in the pathogenesis of inflammatory diseases through chemokine induction, which will promote the migration of inflammatory cells into the lesion area, and MMP-9 induction. PMID: 16882875
15. The specific expression of VSIG4 on resting macrophages suggests that VSIG4 may be important for the maintenance of T cell unresponsiveness in healthy tissues. PMID: 17016562
16. CRIg is not only a phagocytic receptor, but also a potent inhibitor of the alternative pathway convertases PMID: 17051150
