Allgemeine Beschreibung
Die Löslichkeit natürlicher Cyclodextrine ist sehr gering. Ende der 1960er Jahre wurde entdeckt, dass die Löslichkeit durch chemische Substitutionen an den 2-, 3-, und 6-Hydroxylgruppen stark erhöht werden kann. Bei den meisten chemisch modifizierten Cyclodextrinen kann eine Konzentration von 50 % (w/v) in Wasser erreicht werden.

How does Methyl-β-cyclodextrin, Product C4555, work to solubilize products that have minimal solubility in aqueous solutions for use in cell culture?
1 answer-
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.

What is the molecular weight of Methyl-β-cyclodextrin, Product No. C4555?
1 answer-
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.
