Product Overview

Recombinant Human TNFSF18 protein(AA Gln 50-Ser 177)(Accession # AAH69319.1) is expressed from human 293 cells (HEK293). This protein carries a polyhistidine tag at the N-terminus.

Expression System

HEK293

Species

Human

Tag

N-His Tag

Form

Lyophilized from sterile PBS, pH7.4, 10% trehalose.

Molecular Mass

This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 20.5 kDa. The protein migrates as 23 kDa and 26 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Gln 50-Ser 177

Endotoxin

Less than 1.0 EU per ug by the LAL method.

Purity

>90% as determined by SDS-PAGE.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.

SDS-PAGE

Human GITR Ligand, 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%.

Bioactivity-ELISA 1
