laurdan

Description

Laurdan (6-dodecanoyl-2-dimethylaminonaphthalene) is a fluorescent dye that is commonly used to study membrane fluidity and organization in biological systems. It is synthesized through a multi-step process that involves coupling dodecanoic acid with 2-dimethylaminonaphthalene. Laurdan exhibits a unique property of exhibiting different fluorescence emission spectra depending on the polarity of its environment. In more fluid and less polar environments, Laurdan emits blue fluorescence, while in more rigid and polar environments, it emits green fluorescence. This sensitivity to membrane fluidity makes Laurdan a valuable tool for studying membrane dynamics, phase transitions, and the effects of various factors, including temperature, lipid composition, and the presence of proteins, on membrane organization. Laurdan is widely used in various research fields, such as cell biology, biophysics, and pharmacology, to investigate the role of membrane fluidity in cellular processes, drug delivery, and disease pathogenesis.'

Research Excerpts

Overview

Laurdan is a fluorescent probe sensitive to the increase of hydration in the lipid bilayer that accompanies the gel to liquid crystalline phase transition.

ExcerptReferenceRelevance
"Laurdan is a fluorescent probe that detects changes in membrane phase properties through its sensitivity to the polarity of its environment in the bilayer. "( Use of laurdan fluorescence intensity and polarization to distinguish between changes in membrane fluidity and phospholipid order.

Effects

ExcerptReferenceRelevance
"Laurdan has little effect on the phase transition of DPPC vesicles at the concentration used in the sensor (0.67 mol%); concentrations up to 5.4 mol% only slightly lowered the melting temperature."( Perturbation of the chain melting transition of DPPC by galactose, agarose and Laurdan as determined by differential scanning calorimetry.

Alzheimer Disease
A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.

Akinetic-Rigid Variant of Huntington Disease
[description not available]		02.1710
Huntington Disease
A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)		02.1710
