Active Recombinant Full Length Human RBP4 protein, His-tagged

• Cat.No.: RBP4-836H
• Product Overview: Recombinant Human RBP4 protein(NP_006735.2)(Met1-Leu201), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.2Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured by its ability to bind all-trans retinoic acid. The binding of retinoic acid results in the quenching of Trp fluorescence in RBP4.The 50% binding concentration (BC50) is > 1.0 µM.
• Molecular Mass: The recombinant human RBP4 consists of 194 amino acids after removal of the signal peptide and migrates as an approximately 23 kDa protein as predicted.
• Protein length: Met1-Leu201
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 85 % 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.
