Scientific Background:PD-L1, also known as B7-H1 and CD274, is a 290 amino acid transmembrane glycoprotein in the B7 family of immune regulatory molecules. It has an extracellular domain that can interact with PD-1, which belongs to the CD28/CTLA4 family expressed on activated lymphoid cells. The PD1/PD-L1 interaction ensures that activation of the immune system occurs at the appropriate time. This will minimize the possibility of chronic autoimmune inflammation. PD-L1 is known to inhibit proliferation of T cells via apoptosis. It also plays an important role in arresting cell-cycle progression. This makes PD-L1 an attractive therapeutic target for cancer and immunologic diseases.

PD-L1 (human), (recombinant) PD-1-Activity-Fig3
PD-L1 (Prod. No. ENZ-PRT223) was coated onto high binding plates at 10ug/mL. PD-1:human Fc was titered into the assay. The reactions were incubated for 1 hour at room temperature. The plates were washed 3X. Goat anti human IgG-HRP was added into the wells and the plate was incubated for 1 hour then washed 3X. TMB substrate was added. The reaction was stopped with 1M HCL and the plate was read at OD450nm. PD-1 binding to PD-L1 is in the range of 10 – 10,000 ng/ml.
