Product Description |
Recombinant Canine PD-1/PDCD1 Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains Leu25-Val170. |
Product Background |
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. |
