Recombinant Human CD274 protein(Met1-Thr239), His-tagged, Biotinylated

• Cat.No.: CD274-1081H
• Product Overview: Biotinylated Recombinant N-terminal segment (Met1-Thr239) of the extracellular domain of Human B7-H1 (NP_054862.1) was expressed in HEK293 with a C-terminal polyhistidine tag.

Specification

• Source: HEK293
• Species: Human
• Tag: C-His
• Protein length: Met1-Thr239
• Conjugation/Label: Biotin
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized Human PD-1 His & hFc at 2 μg/ml (100 μl/well) can bind Human PD-L1 His, Biotinylated, the EC50 of Human PD-L1 His, Biotinylated is 50-300 ng/mL.
• Molecular Mass: The recombinant mature human B7-H1 comprises 232 amino acids and predicts a molecular mass of 26.8 kDa. As a result of glycosylation, the human B7-H1 migrates as an approximately 35-38 kDa protein in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 95% as determined by SDS-PAGE.
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
