HPLC analysis of Nucleotides in Infant Formula

The concentration of free nucleotides in human milk is significantly higher than in bovine milk. It was demonstrated that infants who received nucleotides in their formula were less likely to have diarrhea and also had better responses to vaccination, producing more antibodies and other immune cells (Carver et al., 1991; Pickering et al., 1998). Most milk formulas are supplemented with nucleotides to increase the concentration to a level that is similar to the concentration found in human milk.

NOVOCIB offers analytical service for quantification of dietary nucleotides in baby milk powder by UV-HPLC. This high performance liquid chromatography analysis of bases, nucleosides and nucleotides consists in:

  • Sample extraction by SPE procedure;
  • Run of extracted samples in ion-paired HPLC (Agilent 1100);
  • Bases, nucleosides and nucleotides quantification (peak area at 254nm, Agilent Software) Separation by ion-paired
  • Recovery  study (every sample is analysed twice with and without added bases, nucleosides and nucleotides standards)
  • Delay: 5 working days
