METHOD VERIFICATION
PD-1 [BIOTINYLATED]:PD-L1 BINDING IN THE ABSENCE OF INHIBITORS:
Immobilized human PD-L1 protein at 2 μg/mL (100 μL/well) can bind human PD-1-Biotin with a linear range of 0.01875-0.3 μg/mL when detected by Streptavidin-HRP. Background was subtracted from data points before curve fitting.
INHIBITION OF PD-1 [BIOTINYLATED] : PD-L1 BINDING BY ANTI-PD-1 NEUTRALIZING ANTIBODY
Serial dilutions of anti-PD-1 neutralizing antibody (1:2 serial dilutions, from 10 μg/mL to 0.078 μg/mL) was added into PD-L1 : PD-1-Biotin binding reactions. The assay was performed according to the above described protocol. Background was subtracted from data points prior to log transformation and curve fitting.
Preparation of Standard Serial Dilutions
1) Pipette 480 μL Dilution Buffer into tube Std-1 and 150 μL Dilution Buffer into the remaining tubes (tube Std.-2 to tube Std.-8).
2) Add 20 μL anti-PD-1 neutralizing antibody stock solution (250 μg/mL) to tube Std.-1 to make the final concentration 10 μg/mL. Mix well.
3) To make a 1:2 serial dilutions, pipette 150 μL solution to the next tube as illustrated in Fig.3.
IMPORTANT: Mix thoroughly at each step during the dilution process. - 实验流程

This assay employs a simple colorimetric ELISA platform, which measures the binding between immobilized human PD-L1 and in-house developed biotinylated PD-1 protein. This product is uniquely suitable for rapid high-throughput screening of putative PD-1 and PD-L1 inhibitors. Briefly, we provide you with a human PD-1-Biotin protein, a human PD-L1 protein, an anti-PD-1 neutralizing antibody (as method verified Std.), and Streptavidin-HRP reagent. Your experiment will include 4 simple steps:
- Coat the plate with human PD-L1.
- Add your molecule of interest to the tests.
- Add human PD-1-Biotin to bind the coated human PD-L1.
- Add Streptavidin-HRP followed by TMB or other colorimetric HRP substrate.

- 背景
- Immune checkpoint pathway is a focal point of today's cancer research. PD-1 is one of the best characterized checkpoint proteins. The binding between PD-1 and its ligand PD-L1 suppresses T-cell activation and allows cancer cells to escape from body's immune surveillance. Therefore, the pharmaceutical inhibition of PD-1 or its ligand has been considered a promising strategy by many oncologists.
