Determination of 8-Hydroxy-2 Deoxyguanosine in Pseudomonas Fluorescens Freeze-Dried Exposed to the ROS Using HPLC with Electrochemical Detection Method

Abstract Oxidative DNA damage is involved in the f cell death induced by freeze-dried powder during storage. Cell 8-hydroxy-2’deoxyguanosine (8-oxodG) is widely accepted as a biomarker of the “freeze-dried bacteria” oxidative DNA damage. The aim of this study was to introduce a method for determination 8-oxodG in cell freeze-dried samples using high-performance liquid chromatography with electrochemical detection. In the tested range of 0.5 µmol L-1 to 1.0 nmol L-1, the calibration curve was linear (r2=0.9995) and the limit of detection was 0.05 µmol L-1. The used method did not allow highlighting the presence in the samples of the 8OH within the limits of detection. A more successful method (more sensitive) would be needed to detect possibly the 8OH.

Keywords Reactive Oxygen Species (ROS), DNA, 8-Hydroxy-2 deoxyguanosine.
