PathHunter® U2OS CD86 Ligand Cell Line
Checkpoint Signaling assays are engineered to co-express a ProLink™ (PK) tagged immune checkpoint receptor and an
Enzyme Acceptor (EA) tagged SH2 domain. Ligand engagement leads to receptor activation and phosphorylation,
resulting in SH2-EA recruitment to the receptor, and forcing complementation of the two β-galactosidase enzyme
fragments (EA and PK). The resulting functional enzyme hydrolyzes substrate to generate a chemiluminescent signal.
