• Cat.No.: CD80-1376H
• Product Overview: Biotinylated Recombinant Human CD80 (NP_005182.1)(Met1-Asn242) was expressed in HEK293 with a C-terminal polyhistidine tag followed by an AVI tag.

Specification

• Source: HEK293
• Species: Human
• Tag: C-His&Avi
• Protein length: Met1-Asn242
• 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 CTLA-4 hFc at 2 μg/mL (100 μL/well) can bind Human B7-1, Biotinylated, the EC50 of Human B7-1, Biotinylated is 60-320 ng/mL.
• Molecular Mass: The recombinant Human CD80 consists of 234 amino acids and predicts a molecular mass of 27.12 kDa. It migRates as an approximately 48.86 kDa band 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.
