1-palmitoyl-2-stearoyl-(7-doxyl)-sn-glycero-3-phosphocholine

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 [Smirnova et al, 2007] and as fluorescent quenchers in lipid bilayer structural studies [Kondo et al, 2008].
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 [Wu and Gaffney, 2006]. For liposome preparations in fluorescent quenching measurements, dissolve the doxyl lipid in 150 µl absolute ethanol for a concentration of 40.3 mM [Kondo et al, 2008, supplemental info found at http://pubs.acs.org/doi/suppl/10.1021/ja804929m/suppl_file/ja804929m_si_001.pdf].
