Recombinant CHO-K1 cells constitutively expressing woodchuck (groundhog, Marmota monax) PD-L1 (Programmed Cell Death 1 Ligand 1, CD274, B7 homolog 1 (B7- H1), GenBank accession # HQ403651) and an engineered T cell receptor (TCR) activator.
Mycoplasma testing: The cell line has been screened using the PCR-based VenorGeM Mycoplasma Detection kit (Sigma-Aldrich, #MP0025) to confirm the absence of Mycoplasma species.
Host Species: hamster
Supplied as Each vial contains ~2.5 x 10^6 cells in 1 ml of 10% DMSO.
Background
The binding of Programmed Cell Death Protein 1 (PD-1), a receptor expressed on activated T-cells, to its ligands, PD-L1 and PD-L2, negatively regulates immune responses. The PD-1 ligands are found on most cancers, and PD-1:PD-L1/2 interaction inhibits T cell activity and allows cancer cells to escape immune surveillance. The PD-1:PD-L1/2 pathway is also involved in regulating autoimmune responses, making these proteins promising therapeutic targets for a number of cancers, as well as multiple sclerosis, arthritis, lupus, and type I diabetes.
Application
Screen for activators or inhibitors of PD-1 signaling in a cellular context Screen PD-L1 antibodies for binding affinity Characterize the biological activity of PD-1 interactions with PD-L1
