一般描述
Phosphatidylcholine (PC) is a strong bilayer-forming lipid. It the most common phospholipid in mammalian membranes. It is also an important component of the mucosal layer of the colon.
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.
应用
16:0-16 Doxyl PC has been used as a spin probe in electron spin resonance spectroscopy.
生化/生理作用
Phosphatidylcholine (PC) functions as a surfactant within the mucus to form a hydrophobic surface to inhibit bacterial penetrance. It is used to treat fat embolism. Phosphatidylcholine lowers the levels of cholesterol and triglycerides.
包装
5 mL Clear Glass Sealed Ampule (810604P-1mg)
制备说明
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.
