一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。

资料参考

2-Hydroxypropyl-β-cyclodextrin is a cyclic oligosaccharide containing 7 glucopyranose units, with an average of one hydroxypropyl group per unit. The circular arrangement of the glucose units forms a torus-shaped ring configuration, and CH2groups and ether linkages of the molecule face the hollow interior of the configuration, which leads to a nonpolar cavity and a polar exterior. When a compound with appropriate geometry and 2-hydroxypropyl-β-cyclodextrin are in the same solution, the nonpolar aromatic parts of that compound tend to interact with the nonpolar interior of the 2-hydroxypropyl-β-cyclodextrin molecule. This complexation isolates the aromatic parts of that compound from the water, thereby increasing its aqueous solubility. 2-Hydroxypropyl-β-cyclodextrin has been widely used in improving the aqueous solubility of a variety of compounds, especially those containing a phenyl group, a group encompassing many drugs.
