This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 51.3 kDa. The protein migrates as 60-75 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human PD-L1, 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 95%.
The purity of Human PD-L1, Fc Tag (Cat. No. PD1-H5258) was more than 90% and the molecular weight of this protein is around 115-150 kDa verified by SEC-MALS.
Immobilized Human PD-L1, Fc Tag (Cat. No. PD1-H5258) at 5 μg/mL (100 μL/well) can bind Anti-PD-L1 MAb with a linear range of 0.2-2 ng/mL (Routinely tested).
Loaded Human PD-1, His Tag (Cat. No. PD1-H5221) on HIS1K Biosensor, can bind Human PD-L1, Fc Tag (Cat. No. PD1-H5258) with an affinity constant of 38.9 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
Loaded Human PD-L1, Fc Tag (Cat. No. PD1-H5258) on Protein A Biosensor, can bind Human B7-1, His Tag (Cat. No. B71-H5228) with an affinity constant of 18 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
Loaded Human PD-L1, Fc Tag (Cat. No. PD1-H5258) on Protein A Biosensor, can bind Human Human PD-1, His Tag, low endotoxin (Cat. No. PD1-H522a) with an affinity constant of 4.8 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
Loaded Human PD-L1, Fc Tag (Cat. No. PD1-H5258) on Protein A Biosensor, can bind Human Human PD-1, Strep Tag (Cat. No. PD1-H5284) with an affinity constant of 2.5 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
Flow Cytometry assay shows that Human PD-L1, Fc Tag (Cat. No. PD1-H5258) can bind to 293 cell overexpressing human PD-1. The concentration of PD-L1 used is 10 μg/mL (Routinely tested).
FACS analysis shows that the binding of Human PD-L1, Fc Tag (HPLC-verified) to 293 overexpressing PD-1 was inhibited by increasing concentration of neutralizing Anti-PD-L1 antibody. The concentration of PD-L1 used is 10 μg/mL. The IC50 is 12.92 μg/mL (Routinely tested).
Immobilized cell surface PD-1 (5x104 of cells per well) can bind Human PD-L1, Fc Tag (Cat. No. PD1-H5258) with an EC50 of 0.029 μg/mL (Routinely tested).
