Complete Protocol UniProt ID (Human) Q15116. As previously mentioned, while highly effective, anti-PD1/PDL1 therapies engender little to no benefit for many patients, and patients can be stratified as being sensitive, or as displaying either primary or acquired resistance , .For example, the posterchild for success in anti-PD1 therapy, and also the example for which clinical data are most mature, is melanoma. The PD-1:PD-L1 Homogeneous Assay Kit is designed to measure the inhibition of PD-1 binding to PD-L1.
