This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 22.4 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

No activity loss was observed after storage at:
Human TNFSF11, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
Immobilized Human RANK, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. RAK-H5251) at 0.5 μg/mL (100 μL/well) can bind Human TNFSF11, His Tag (Cat. No. RAL-H5240) with a linear range of 0.4-6 ng/mL (QC tested).
Anti-TNFSF11 (human IgG1) captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind Human TNFSF11, His Tag (Cat. No. RAL-H5240) with an affinity constant of 0.274 nM as determined in a SPR assay (Biacore T200) (Routinely tested).
