Description générale
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.
Phosphatidylcholine (PC), a strong bilayer-forming lipid is the most common phospholipid in mammalian membranes. Several prokaryotic and eukaryotic pathogens has phosphorylcholine as its structural constituent.
Actions biochimiques/physiologiques
Phosphorylcholine (PC) possesses immunomodulatory properties.
Conditionnement
5 mL Clear Glass Sealed Ampule (810602P-1mg)
Notes préparatoires
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.

Phosphorylcholine (PC) is a structural component of a variety of prokaryotic and eukaryotic pathogens. In some cases, PC in infectious agents can benefit the infected host due to its targeting by both the innate and adaptive immune responses. However, as

The putative substrate-binding site in lipoxygenases is long and internal. There is little direct evidence about how the unsaturated fatty acid substrates enter and move within the cavity to position themselves correctly for electron transfer reactions with the catalytic non-heme

The positively charged nitroxide spin label, 2,2,6,6-tetramethyl-piperidine-N-oxyl-4-trimethylammonium (Cat1), was encapsulated in two types of liposomes, phosphatidylserine/phosphatidylcholine (PS/PC) and phosphatidylserine/distearoylphosphatidylcholine/dipalmitoylphosphatidyl choline (PS/DSPC/DPPC). The liposomes were incubated with mouse thymus-bone marrow (TB) cells to study the uptake and metabolism of nitroxides entrapped
