| Specificity Profile | More Information |
|
The specificity of PD-1 Monoclonal Antibody (CSB0023) was tested on the Membrane Proteome Array® and shown to be specific for human PD-1. The Membrane Proteome Array® contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array® represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |

HEK-293F cells transiently transfected with human PD-1 were stained with PD-1 Monoclonal Antibody (CSB0023) (green) or isotype control antibody (gray), followed by AlexaFluor 647- conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with PD-1 Monoclonal Antibody (CSB0023) (blue). | |

PD-1 is single-pass transmembrane protein and an immune-inhibitory receptor on activated T-cells. PD-1 plays a role in regulation of T-cell functions and is important for protecting against autoimmunity. PD-1 can also inhibit anti-microbial and anti-tumor immunity, and is expressed in various tumors, including melanomas.
