Human PD1 / PDCD1 Protein (His Tag)

Species : Human

Synonyms : CD279,hPD-1,hPD-l,hSLE1,PD-1,PD1,SLEB2

Host : HEK293 Cells

Purity :> 95 % as determined by SDS-PAGE

Activity : 1. Measured by its binding ability in a functional ELISA. Immobilized human PD-1 at 10 £gg/ml (100 £gl/well) can bind recombinant human B7-H1 / PD-L1 / Fc chimera with a linear range of 0.02-0.4 £gg/ml.
2. Labeled biotin to PD-1 Protein, Human, Recombinant (His Tag) by a certain molar ratio; Using the Octet RED System, the affinity constant (Kd) of PD-1 Protein, Human, Recombinant (His Tag), Biotinylated(Cat. 10377-H08H-B) bound to Keytruda was 4.7 nM.
