Recombinant Human TNFRSF1B extracellular domain (Met 1-Asp 257) (NP_001057.1), fused with a C-terminal polyhistidine tag, was produced in Human Cell.
Lyophilized from sterile PBS, pH 7.4
The recombinant human TNFRII comprises 246 amino acids and has a calculated molecular mass of 26.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh TNFRII is approximately 42-45 kDa due to glycosylation.
< 1.0 eu per μg of the protein as determined by the LAL method.
Samples are stable for up to twelve months from date of receipt at -70oC.
Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4oC before opening to recover the entire contents.
