• Cat.No.: CD274-1176H
• Product Overview: Recombinant Human PD-L1/B7-H1 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Phe19-Arg238 [Accession | Q9NZQ7-1 ].

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 19-238 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
• Bio-activity: Immobilized Human PD-L1, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-PD-L1 Antibody, hFc Tag with the EC50 of 0.92ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 26 kDa. Due to glycosylation, the protein migrates to 35-42 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
• 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.
