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.
Activity	Immobilized Human PD-1, His Tag at 1ug/ml (100ul/Well). Dose response curve for Anti-PD-1 Antibody, hFc Tag with the EC50 of 6.9ng/ml determined by ELISA (QC Test). The affinity constant of 2.20 uM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
