Optimized DNA sequence  encoding  extracellular domain of Human Programmed cell death protein 1 PD-1 (PRO21 - GLN167) including a C-terminal His tag was expressed in HEK293 cells.

Molecular weight:

Recombinant human PD-1 (PDCD1) is a protein consisting of 150 amino acid residue subunits,due to glycosylation migrates as an approximately 40kDa protein on reduced SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC
Biological Activity:
The activity was tested by the ability of immobilized recombinant Human PD-1  to bind recombinant human PD-L1 within a linear range of 100-1000ng/ml in ELISA.
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant Human PD-1 is lyophilized  from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

A quick spin of the vial followed by reconstitution in sterile PBS pH 7.4 to a concentration not less than 0.2 mg/mL. Solubilize for 1hr at room temp with gentle mixing.

Recombinant  PD-1 can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.It is recommended to add 0.1% HSA or BSA for long term storage.

Avoid repeated freeze/thaw cycles.

The programmed cell death-1 (PD-1) is an inhibitory surface receptor expressed by T cells, B cells, natural killer T cells, monocytes, and dendritic cells (DC), but not by resting T cells. PD-1 binds two ligands, programmed cell death ligand 1 (PD-L1) and PD-L2 called B7-H1 and B7-DC, respectively . Tumors can use the PD-1 inhibitory pathway to silence the immune system
