Name : Biotinylated Cynomolgus/Rhesus macaque PD-L1/B7-H1 Protein (Primary Amine Labeling)
Product Source :
Recombinant Biotinylated Cynomolgus/Rhesus macaque PD-L1/B7-H1 Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus. It contains Phe19-Arg238.[Accession | G7PSE7]
Molecular Weight :
The protein has a predicted MW of 26 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Supplied as 0.22μm filtered solution in PBS (pH 7.4).
Reconstitution :
Storage and Stability :
Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :

SEC-HPLC The purity of Biotinylated Cynomolgus/Rhesus macaque PD-L1 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Biotinylated Cynomolgus/Rhesus macaque PD-L1, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-PD-L1 Antibody, hFc Tag with the EC50 of 4.0ng/ml determined by ELISA.
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.
Synonyms :
CD274; PDL1; PD-L1; PD-L1B7 homolog 1;B7-H; B7H1; B7-H1; PDCD1L1; PDCD1LG1
