Greater than 95% as determined by SDS-PAGE.
Less than 1.0 EU/ug as determined by LAL method.
Measured by its binding ability in a functional ELISA. Immobilized Human VSIG4 at 2 μg/ mL can bind Anti-VSIG4 recombinant antibody (CSB-RA896869MA1HU), the EC50 is 51.14-68.73 ng/mL.
Homo sapiens (Human)
Target Protein Sequence
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.
Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
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.
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
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.
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Datasheet & COA
Please contact us to get it.
This Human VSIG4 recombinant protein was produced in Mammalian cell, where the gene sequence encoding human VSIG4 (20-283aa) was expressed with the C-terminal 10xHis tag. The purity of this VSIG4 protein was 95%. The activity has been validated.
VSIG4 acts through complement receptors and phagocytosis. As an important effector system and effector amplification system in the body, the complement system can promote the phagocytosis of pathogens by macrophages by acting on the surface of pathogens, destroying the cell membranes of pathogens, and regulating the surface molecules of pathogens.
