Stable Cell Lines for DNA Repair Assays

These HR/NHEJ kits are cell based, meaning they have the HR or NHEJ GFP reporters pre-installed.  A single plasmid (I-Sce1) is transfected to activate repair. Please see this table for a summary and comparison/application of each kit.

Transfection-based DNA Repair Assays

Transfection-based HR and NHEJ kits use transient transfections to make a pool of cells containing the DNA reporters to allow the investigator to interrogate the 2 major DNA repair pathways. The advantages are:

  •  It uses GFP readout to measure the efficiency of repair.
  • There is zero background when repair is blocked or inhibited
  • The reporters for HR or NHEJ can be installed in virtually any cell line that can be transiently transfect
  • It is rapid and robust
  • It is ideal for drug screens to find novel inhibitors of HR/NHEJ
  • The kits are highly specific and can only report HR or NHEJ
  • Readout GFP can be done by FACS or Imaging
  • Entire pathway can be followed by live imaging in viable cells
  • Ideal to track repair kinetics at the single cell level

HR Kit: DR-3050

NHEJ Kit: DRT-5050
