This protein carries a mouse IgG1 Fc tag at the C-terminus , and has a calculated MW of 51.6 kDa. The predicted N-terminus is Phe 19. The reducing (R) protein migrates as 65-85 kDa in SDS-PAGE due to glycosylation and the non-reducing (NR) protein migrates as 130-170 kDa.
>92% as determined by SDS-PAGE.
>90% as determined by SEC-HPLC.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

No activity loss is observed after storage at:
Human PD-L1, mouse IgG1 Fc Tag on SDS-PAGE under reducing (R) and no-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 92%.
The purity of Human PD-L1 Protein, mouse IgG1 Fc Tag, low endotoxin (Cat.# PD1-H52A3) was more than 90% as determined by SEC-HPLC.
Immobilized Human PD-L1, mouse IgG1 Fc Tag (Cat. No. PD1-H52A3) at 5 μg/mL ( 100 μl/well ) can bind Biotinylated Human PD-1, His Tag & Fc tag (Cat. No. PD1-H82F2) with a linear range of 0.05-0.2 μg/mL (Routinely tested).
Flow Cytometry assay shows that recombinant human PD-L1 (Cat.No. PD1-H52A3) can bind to 293 cell overexpressing human PD-1. The concentration of PD-L1 used is 0.1ug/ml (Routinely tested).
FACS analysis shows that the binding of PD-L1 to 293 overexpressing PD-1 was inhibited by increasing concentration of neutralizing anti-hPD1 antibody. The concentration of PD-L1 used is 1ug/ml. The IC50 is 0.145 μg/mL (Routinely tested).
