Product Overview
Recombinant Human PDCD1 protein(AA Leu 25-Gln 167)(Accession # Q15116-1) is expressed from human 293 cells (HEK293). This protein carries a mouse IgG2a Fc tag at the C-terminus.
Expression System
HEK293
Species
Human
Tag
C-mFc Tag
Form
Lyophilized from sterile PBS, pH7.4, 10% trehalose.
Molecular Mass
This protein carries a mouse IgG2a Fc tag at the C-terminus. The protein has a calculated MW of 42.5 kDa. The protein migrates as 55-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Protein length
Leu 25-Gln 167
Endotoxin
Less than 0.1 EU per ug by the LAL method.
Purity
>95% 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.
