Scientific Background
Receptor for TNFSF9/4-1BBL. Possibly active during T cell activation.
Product Description
E. coli ExpressionRecombinant Human Tumor necrosis factor receptor superfamily member 9 protein (TNFRSF9), partial (Active) is a recombinant protein expressed in E. coli and purified to >97% as determined by SDS-PAGE. as determined by SDS-PAGE. Supplied as Lyophilized powder, tag-free. For research use only.
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.

Functional Activity
Biologically Validated
Fully biologically active when compared to standard. The biological activity is determined by its inhibitory effect of IL-8 production using human peripheral blood mononuclear cells. About 90 % of inibition was seen using a concentration of 1 µg for both 4-1BB Ligand and 4-1BB Receptor.
