Description générale

Dehydroergosterol (DHE) is a fluorescent sterol that possesses similar biophysical properties as cholesterol. It is found in yeast cells and other fungi.

Application

Dehydroergosterol (DHE) is suitable for the transfer of DHE from a population of donor (LD) to acceptor (LA) liposomes.

Actions biochimiques/physiologiques

Dehydroergosterol (DHE) is used for the visualization of intracellular traffic and intracellular transport kinetics.

Although dehydroergosterol (DHE) is one of the most commonly used cholesterol (CHOL) reporters, it has remained unclear why it performs well compared with most other CHOL analogues and what its possible limitations are. We present a comprehensive study of the

We describe a simple but sensitive fluorescence method to accurately detect the esterification activity of lecithin:cholesterol acyltransferase (LCAT). The new assay protocol employs a convenient mix, incubate, and measure scheme. This is possible by using the fluorescent sterol dehydroergosterol (DHE)

Dehydroergosterol (DHE) is an intrinsically fluorescent sterol with absorption/emission in the ultraviolet (UV) region and biophysical properties similar to those of cholesterol. We compared the potential of UV-sensitive low-light-level wide-field (UV-WF) imaging with that of multiphoton (MP) excitation microscopy to
Olav Garvik et al.
Chemistry and physics of lipids, 159(2), 114-118 (2009-05-30)
The fluorescent sterol dehydroergosterol (DHE) is often used as a marker for cholesterol in cellular studies. We show by vesicle fluctuation analysis that DHE has a lower ability than cholesterol to stiffen lipid bilayers suggesting less efficient packing with phospholipid
