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

General description

Phosphorus-31 nuclear magnetic resonance (31P NMR) is used to investigate acid-labile phosphorylation of histone H4. 31P NMR detects phosphorylated histidine residues in in vitro enzymatically phosphorylated H4. The source of kinase is nuclei from either regenerating rat liver or Walker-256

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
