Product Description
Cat
IMP-055
Official Symbol
TNFSF4
Product Overview
Recombinant Human TNFSF4 protein(AA Gln 51-Leu 183)(Accession # NP_003317) is expressed from human 293 cells (HEK293). This protein carries a human IgG1 Fc tag at the N-terminus.
Expression System
HEK293
Species
Human
Tag
N-Fc Tag
Form
Lyophilized from sterile PBS, pH7.4, 10% trehalose.
Molecular Mass
This protein carries a human IgG1 Fc tag at the N-terminus. The protein has a calculated MW of 42.4 kDa. The protein migrates as 53-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Protein length
Gln 51-Leu 183
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
SDS-PAGE

Human OX40 Ligand, Fc 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%.
