Recombinant Human CD274 protein, C-hFc Tag, Biotinylated
Product Description
Cat
IMP-468
Official Symbol
CD274
Product Overview
Biotinylated Recombinant Human CD274 (NP_054862.1) (Met1-Thr239) was expressed in HEK293, fused with C-terminal fused Fc region of Human IgG1.
Description
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.
Expression System
HEK293
Species
Human
Tag
C-hFc Tag
Predicted N Terminal
Phe 19
Form
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass
The recombinant human CD274 consists of 459 amino acids and predicts a molecular mass of 52 kDa. As a result of glycosylation, it migrates as an approximately 73.6 kDa protein in SDS-PAGE under reducing conditions.
Protein length
Met1-Thr239
Endotoxin
< 1.0 EU per μg protein as determined by the LAL method.
Purity
> 95 % as determined by SDS-PAGE.
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
