LXRepair technology has been developed to establish the DNA Repair Enzyme Signature.

DNA Repair enzymes contained in a biological sample react with series of lesion-containing DNA on a biochip. The repair reaction occurring at each lesion site is measured by fluorescence analysis.

LXRepair technology combines:

  • A multiplexed approach enabling the simultaneous screening of several enzymatic DNA Repair activities from a single sample on a microsupport
  • A quantitative detection

  • Multiple detection
  • System vision
  • Comparative quantification of different DNA Repair pathways
