General description
Phosphoric acid solution is widely used NMR reference standard.
Application
Phosphoric acid may be employed in the following studies:
- As standard for the determination of phosphorus-31 nuclear magnetic resonance (31P NMR) chemical shifts of the common phospholipids.
- As external standard for the analysis of lipid composition of human white matter by 31P NMR spectroscopy.
- As external standard during the acid-labile phosphorylation of histone H4 by 31P NMR spectroscopy.
- As reference standard to investigate the surface species present on silica/alumina-supported sodium phosphates by pre- and postreaction MAS31P-NMR and FTIR spectroscopies.
Features and Benefits
31P sensitivity
Packaging
Coaxial 4.2 mm O.D. x 8 in. tube (equivalent to Wilmad WGS-5BL) designed to be used inside a 5 mm x 7 in. NMR tube.

In order to study the lipid composition of human white matter, we have developed a 31P NMR spectroscopy method, which allows the determination and quantitation of the main phospholipids found in biological membranes. The technique is based upon the use

Journal of lipid research, 29(5), 679-689 (1988-05-01)
The common phospholipids from biological sources were quantitated using phosphorus-31 nuclear magnetic resonance (NMR) spectroscopy in conjunction with an analytical reagent composed of two parts: 1) 2 ml of reagent chloroform in which was dissolved 0.01-100 mg of crude tissue
