PD-1/PDCD1[Biotin], His & Avi, Human

Programmed cell death protein 1, also known as PD-1 and CD279 , is a protein found on the surface of cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self tolerance by suppressing T cell inflammatory activity.

Purity > 95% as determined by Bis­Tris PAGE 
> 95% as determined by HPLC
Endotoxin Level Less than 1EU per μg by the LAL method.
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized PD-1/PDCD1[Biotin], His & Avi, Human at 1μg/ml (100μl/Well) on streptavidin (5μg/ml) precoated plate can bind Human PD­L1, hFc Tag. Test result was comparable to standard batch.
Expression System HEK293
Theoretical Molecular Weight 18.9 kDa
Apparent Molecular Weight Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
