Product Details

Purification tag / Conjugate: This PD-L1 protein is labelled with Fc Tag.

Purpose: Recombinant Human PD-L1/B7-H1/CD274 Protein (Fc Tag)(Active)

Sequence: Met 1-Thr 239

Characteristics: 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 C-terminal fused Fc region of human IgG1.

Endotoxin Level: < 1.0 EU per μg as determined by the LAL method.

Biological Activity Comment: Measured by its binding ability in a functional ELISA. Immobilized human PD-1 at 10 μg/ml (100 μl/well) can bind recombinant human B7-H1 / PD-L1 / Fc chimera with a linear range of 0.02-0.4 μg/ml.

Target: PD-L1 (CD274 (PD-L1))

Alternative Name: PD-L1/B7-H1/CD274

Background:

Background: 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.Immune CheckpointImmune Checkpoint Blockade: Blocking Antibodies   Immune Checkpoint Blockade: PD-L1 / B7-H1 / CD274 Blocking AntibodiesImmune Checkpoint Detection: Antibodies   Immune Checkpoint Detection: ELISA Antibodies   Immune Checkpoint Detection: IHC Antibodies   Immune Checkpoint Detection: ICC Antibodies   Immune Checkpoint Detection: FCM Antibodies   Immune Checkpoint Detection: WB AntibodiesImmune Checkpoint Proteins   PD-L1 / B7-H1 / CD274 Immune Checkpoint ProteinsImmune Checkpoint Targets   Co-inhibitory Immune Checkpoint Targets Immunotherapy   Cancer Immunotherapy   Targeted Therapy
