General description
Avanti′s nitroxide spin product listing is a group of compounds designed to act as membrane probes. A variety of positions down the hydrophobic chain are labeled with the nitroxide functional groups to allow probing the membrane at various depths. These compounds have been synthesized from 1-palmitoyl-2-hydroxy-sn-glycerol-3-phosphocholine with the product being purified by column chromatography. Various n-doxyl phosphocholines have been recently used as biophysical tools to elucidate membrane trafficking with phosphatidylinositol transfer proteins and as fluorescent quenchers in lipid bilayer structural studies.
Phosphocholine is considered as a precursor molecule. It is formed during the breakdown of phosphatidylcholine metabolism. 10-Doxyl is a spin label probe.
Application
16:0-10 Doxyl PC may be used:
- in vesicles for quenching PT-(1–46)F4W fluorescence
- as vesicle component for tryptophan based fluorescence emission studies
- to probe the oxygen and Ni[II] ethylenediaminediacetic acid (NiEdda) accessibilities inside liposomes
Biochem/physiol Actions
Phosphatidylcholine (PC) functions as a surfactant within the mucus to form a hydrophobic surface to inhibit bacterial penetrance.
Packaging
5 mL Clear Glass Sealed Ampule (810603P-1mg)
Preparation Note
Product use: To prevent aggregation, prepare water-based solutions of 2 mM stock solutions of n-DOXYL PCs and store in plastic. Dilute stock solutions to 0.03- 0.1 mM solutions for EPR studies. For liposome preparations in fluorescent quenching measurements, dissolve the doxyl lipid in 150 μl absolute ethanol for a concentration of 40.3 mM , Additional supplemental information.

Spin-labeled lipids are commonly used as fluorescence quenchers in studies of membrane penetration of dye-labeled proteins and peptides using depth-dependent quenching. Accurate calculations of depth of the fluorophore rely on the use of several spin labels placed in the membrane
