Product Description	Recombinant Human PD-1/PDCD1 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Leu25-Gln167.
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.
Product Category	Recombinant Protein / Antibody discovery / Immune checkpoint proteins

Protein	PD-1/PDCD1
Synonyms	PDCD1; PD1; CD279; SLEB2; PD-1
Accession	Q15116-1
Species	Human
Biotinylated	no
Amino Acid Range	Leu25-Gln167
Molecular Weight	The protein has a predicted MW of 17 kDa. Due to glycosylation, the protein migrates to 38-50 kDa based on Bis-Tris PAGE result.
