3-dodecanoyl-NBD Cholesterol

一种荧光标记的胆固醇，其亲水性NBD荧光团附着在胆固醇的亲水末端，通过一个12碳的间隔分子与胆固醇分离；这种设计使胆固醇能够正确地定向在膜双层中，而荧光标记则暴露在双层外部；NBD的激发/发射波长分别为465/535 nm。A fluorescently tagged cholesterol with the hydrophilic NBD fluorophore attached to the hydrophilic end of cholesterol, separated by a 12-carbon spacer; allows the cholesterol to properly orient in membrane bilayers while the fluorescent tag is presented outside of the bilayer; NBD ex/em = 465/535 nm, respectively.
