Application

Girard′s reagent T may be used as a derivatizing reagent for the determination of 5-Formyl-2′-deoxyuridine in cellular DNA samples using liquid chromatography–tandem mass spectrometry (LC–MS/MS) technique. Reducing saccharides can be derivatized by Girard′s reagent T and this can be analyzed by matrix-assisted laser desorption/ionization coupled to time of flight mass spectrometry (MALDI-TOF-MS) technique.

Features and Benefits

  • Girard′s reagent T is a chemical derivatization reagent for LC-MS.
  • It has carbonyl functional group possessing high proton (cation) affinity that stabilizes a positive charge.       
  • It is commonly used in the derivatization of nucleosides.        
  • Derivatization reactions in mass spectrometry are used to improve ionization efficiency.
  • Derivatization can enhance precise quantitative analysis for profiling of relatively small analyte molecules, particularly in metabolomics.

Nucleoside 5-formyl-2'-deoxyuridine (FodU) is a major thymidine lesion generated by reactive oxygen species. In vitro and in vivo replication studies revealed that FodU can be mutagenic. A reliable and sensitive quantification method is, therefore, important for assessing the biological implications
