How to use

In Vitro:

PD-1/PD-L1-IN 3 (0.1 nM-10 μM) inhibits the binding of PD-1 and CD80 to PD-L1, with IC50s of 5.60 nM and 7.04 nM. PD-1/PD-L1-IN 3 blocks the binding of recombinant PD-L1-Ig to Jurkat-PD-1 cells, and also block binding of recombinant PD-1-Ig to either L2987 or LK35.2-hPD-L1, with IC50s of 26 nM, 12 nM, and 3.5 nM, respectively. PD-1/PD-L1-IN 3 (0.001-100 μM) promotes IFN secretion by CMV-specific T cells in a dose-dependent manner, with an EC50 of 400 nM.
