Recombinant Human PDCD1 fused with His tag at N-terminal was expressed in HEK293.
Lyophilized from sterile PBS, pH 7.4
Measured by its binding ability in a functional ELISA. Immobilized human PD-1 at 10 μg/ml (100 μl/well) can bind recombinant human B7-H1 / PD-L1 / Fc chimera with a linear range of 0.02-0.4 μg/ml.
The recombinant mature human PD1 consists of 154 amino acids and has a calculated molecular mass of 17.4 kDa.
< 1.0 EU per μg of the protein as determined by the LAL method
> 95 % as determined by SDS-PAGE
Samples are stable for up to twelve months from date of receipt at -70 centigrade.
Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
