DNA Damage and Repair Mechanisms


  • UGA-40-MLC ablation system with DPSL-355/14, DL-405, DL-473 and DPSL-543 lasers
  • Zeiss AxioObserver Z1 with Spinning Disc unit and four-line laser combiner, AxioCam and Photometrics Evolve cameras (AxioCam used in the experiment)
  • Objective 63x water immersion
UGA-40-MLC ablation system on Zeiss AxioObesrver with SD unit - Zeiss Demo Center, Munich Germany

Experimental information

  • GFP imaging at 488 nm, in spinning disc mode using ZEN Blue software from Zeiss.
  • DNA damage induced by UV ablation at 355 nm. Repair proteins tagged with GFP. As they gather in the damaged areas, the local fluorescence increases and the spots appear brighter in the image.
  • Experiment set up in a high throughput style, without prescreening, in a multiwell plate.
  • Photomanipulation software run in Grid mode. A multi point grid was set up to be run in each well while the sample was continuously imaged. The DNA damage was induced in the nuclei which happened to be located in the light path. The damage locations became more fluorescent during the imaging due to the accumulation of the GFP-tagged repair proteins.
