Cholesterol is a key component of eukaryotic cell membranes and plays a
critical role in membrane organization, fluidity, and function. In
cholesterol-rich lipid raft, numerous membrane proteins and important membrane
activities, including those involved in signal transduction, are found.
In
additiopn to the effect of cholesterol on membrane structure and function, the
interaction of membrane proteins with cholesterol have been reported. Many
membrane proteins, such as G-protein coupled receptors (GPCRs), cholesterol
binding proteins, and amyloid precursor protein require cholesterol binding to
have their proper biological function.
Therefore cholesterol-based
surfactants have become highly sought after. Cholesteryl hemisuccinate is a
water-soluble cholesterol derivative that mimics native cholesterol function
in cell membrane systems.
Cholesterol hemisuccinate and Lauryl Maltose
Neopentyl Glycol (cat. no. 60110) have been shown to easily exchange membrane
proteins into Lipid-Cubic Phase (LPC). Commonly used in combination with
N-Dodecyl-β-D-Maltopyranoside (DDM, cat. no. 60099) for extracting membrane
proteins.
Solubility: 1.2 % in a 6 % water solution of CHAPS
