The approximate molecular weight is 1320 g/mol. The molecular weight can vary from lot to lot due to variation in the methyl content of the product. The molecular weight of this product is dependent on the average number of methyl groups per glucose residue (reported on the lot specific Certificate of Analysis). View the specification sheet above.
This product is tested and found soluble at 50 mg/ml in 1 M NaOH yielding a clear, colorless solution. This product is also soluble in water (150 mg/ml), yielding a clear, colorless solution. Aqueous solutions may be obtained by stirring 30 minutes at room temperature. Alternatively, sonication with cooling may be employed.
Solutions can be sterile filtered using a 0.2 μm membrane. We do not recommend autoclaving the solution. The product as supplied is not sterile.
The cavity diameter of β -cyclodextrins compounds is well-suited for use with molecules the size of hormones, vitamins and many compounds frequently used in tissue and cell culture applications. For this reason, β-cyclodextrin is most commonly used as a complexing agent. Hydrophobic molecules are incorporated into the cavity of cyclodextrins by displacing water. This reaction is favored by the repulsion of the molecule by water. This effectively encapsulates the molecule of interest within the cyclodextrin, rendering the molecule water soluble. When the water soluble complex is diluted in a much larger volume of aqueous solvent, the process is reversed, thereby releasing the molecule of interest into the solution.
