PD-L1 Protein, Human, Recombinant (ECD, His Tag): Product Information
Purity
> 98 % as determined by SDS-PAGE
Endotoxin
< 1.0="" eu="" per="" μg="" of="" the="" protein="" as="" determined="" by="" the="" lal="">
Activity
1. Measured by its binding ability in a functional ELISA. Immobilized human B7-H1 at 20 μg/ml (100 μl/well) can bind human PD1 with a linear range of 0.032-0.8 μg/ml.2. Using the Octet RED System, the affinity constant (Kd) of PD-1 Protein, Human, Recombinant (Fc Tag) (Cat. 10377-H02H) bound PD-L1 Protein, Human, Recombinant (His Tag) (Cat. 10084-H08H) was 19.2nM.
Protein Construction
A DNA sequence encoding the N-terminal segment (Met 1-Thr 239) of the extracellular domain of human B7-H1 (NP_054862.1) was expressed with a C-terminal polyhistidine tag.
Accession#
NP_054862.1
Expressed Host
HEK293 Cells
Species
Human
Predicted N Terminal
Phe 19
Molecule Mass
The recombinant mature human B7-H1 comprises 232 amino acids and predicts a molecular mass of 26.8 kDa. As a result of glycosylation, the human B7-H1 migrates as an approximately 35-38 kDa protein in SDS-PAGE under reducing conditions.
Formulation
Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
Shipping
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

PD-L1 Background Information
Programmed death-1 ligand-1 (PD-L1, CD274, B7-H1) has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. PD-L1/B7-H1 is a member of the growing B7 family of immune molecules and this protein contains one V-like and one C-like Ig domain within the extracellular domain, and together with PD-L2, are two ligands for PD1 which belongs to the CD28/CTLA4 family expressed on activated lymphoid cells. By binding to PD1 on activated T-cells and B-cells, PD-L1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression. Accordingly, it leads to growth of immunogenic tumor growth by increasing apoptosis of antigen specific T cells and may contribute to immune evasion by cancers. PD-L1 thus is regarded as promising therapeutic target for human autoimmune disease and malignant cancers.
