SKU: PD1-CP001

Catalog numberPD1-CP001

HEK293Molecule · PDCD1Molecular weight · 17.53 kDa

Product introduction

Recombinant Cynomolgus PD-1/PDCD1 Protein is expressed in HEK293 cells with a His tag at the C-terminus. It contains amino acid residues Pro21-Gln167 (accession: B0LAJ3).

Product details

Molecular aliases: PDCD1; PD1; CD279; SLEB2; PD-1
Protein length: Pro21-Gln167
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 17.53 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.
Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin: Less than 1 EU per μg by the LAL method.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
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.
Reconstitution: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

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.
