Product Description	Recombinant Human PD-L1/B7-H1 Protein is expressed from HEK293 with mFc (IgG1) tag at the C-Terminus.It contains Phe19-Arg238.
Product Background	B7-H1, also known as PD-L1 and CD274, is an approximately 65 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. PD-L1 has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance.
Product Category	Recombinant Protein / Antibody discovery / Immune checkpoint proteins

Protein	PD-L1/B7-H1
Synonyms	CD274; PDL1; PD-L1; PD-L1B7 homolog 1;B7-H; B7H1; B7-H1; PDCD1L1; PDCD1LG1
Accession	Q9NZQ7-1
Species	Human
Biotinylated	no
Amino Acid Range	Phe19-Arg238
Molecular Weight	The protein has a predicted MW of 50.9 kDa. Due to glycosylation, the protein migrates to 68-75 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human PD-L1, mFc Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human PD-1, hFc Tag with the EC50 of 90.5ng/ml determined by ELISA (QC Test). See testing image for detail.
Product Tag	C-mFc
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU 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	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
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.
