Determined by its ability to bind all trans retinol acids. The binding of RBP4 to all trans retinol acids results in quenching of Trp fluroscence. 0.5M retinol acids/per M RBP4.
RBP-4 His tag was filtered (0.4 um) and lyophilized from 0.5 mg/ml in PBS buffer, pH 7.5.
White lyophilized (freeze-dried) powder.
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Retinol binding protein-4 in sterile deionized water to a working volume of 0.5mg/mL and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
Lyophilized Retinol binding protein-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Retinol binding protein-4 should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
