ACROBiosystems newly added the world's first full length human PD1 protein to an alread extensive archive of PD1 family proteins. The full length protein demonstrates a much higher binding affinity against PDL1 than the PD1 ECD protein.
A representative ELISA result showed that immobilized full length human PD1 (PD1HC214,20 ng/well) can bind with human PDL1 with a linear range of 1.278ng, which is much higher than the PD1 ECD protein (linear range 250ng1,250ng).
We also provide a wide variety of PD1 family proteins from different species. This includes the exclusive PrecisionAvi series of Avitag™ biotinylated PD1, PDL1 and PDL2, the HPLC‐verified products, and the high throughput PD1:PDL1 pathway inhibitor screening assay pair.
