Recombinant Human PDCD1 extracellular domain (Met 1-Gln 167) (NP_005009.2), fused with a C-terminal polyhistidine tag, was produced in Human Cell.
Lyophilized from sterile PBS, pH 7.4
The recombinant mature human PD1 consists of 154 amino acids and has a calculated molecular mass of 18 kDa. As a result of glycosylation, the rhPD1 migrates as an approximately 38-42 kDa protein in SDS-PAGE.
< 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.
