Active Recombinant Mouse RBP4 protein(Met1-Leu201), His-tagged

• Cat.No.: RBP4-211M
• Product Overview: Recombinant Mouse RBP4 (NP_035385.1) (Met 1-Leu 201) was expressed in HEK293, fused with a polyhistidine tag at the C-terminus.

Specification

• Source: HEK293
• Species: Mouse
• Tag: C-His
• Protein length: Met1-Leu201
• 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 ability to bind alltrans retinoic acid. The binding of retinoic acid results in the quenching of Trp fluorescence in RBP4. The 50% binding concentration (BC50) is >0.5 μM.
• Molecular Mass: The secreted recombinant mouse RBP4 comprises 194 amino acids and has a predicted molecular mass of 22.8 kDa as estimated in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the 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.
