WebAug 1, 1996 · In this report we describe the first cross-polarization (CP) magic angle spinning (MAS) phosphorus-31 ( 31 P) NMR investigations of oligonucleotides covalently bound to a solid support. 31 P was chosen as the nucleus of interest because, first, it is 100% naturally abundant and has good sensitivity in the NMR experiment, so that no … http://fluorine.ch.man.ac.uk/research/p31calc.php
P, a beta-emitter (1.71 MeV) with a half-life of 14.3 days, is used routinely in life-science laboratories, primarily to produce radiolabeled DNA and RNA probes, e.g. for use in Northern blots or Southern blots. Because the high-energy beta particles produced penetrate skin and corneas, and because any P ingested, inhaled, or absorbed is readily incorporated into bone and nucleic acids, OSHA requires that a lab coat, disposable gloves, and safety glasses or goggles be worn when work… Phosphorus-31 NMR spectroscopy is an analytical chemistry technique that uses nuclear magnetic resonance (NMR) to study chemical compounds that contain phosphorus. Phosphorus is commonly found in organic compounds and coordination complexes (as phosphines), making it useful to measure P NMR … See more With a gyromagnetic ratio 40.5% of that for H, P NMR signals are observed near 202 MHz on an 11.7-Tesla magnet (used for 500 MHz H NMR measurements). Chemical shifts are referenced to 85% phosphoric acid, … See more P-NMR spectroscopy is useful to assay purity and to assign structures of phosphorus-containing compounds because these signals are well resolved and often occur at characteristic frequencies. Chemical shifts and coupling constants span a … See more P-NMR spectroscopy is widely used for studies of phospholipid bilayers and biological membranes in native conditions.
