Fluorescent Cell Lines for Detection of DNA Damage

The Enhanced Level of Genomic instability 1 (ELG1) protein suppresses genomic instability caused by DNA damage. Cell lines for studying human ELG1 (hELG1) have been established that stably express a fusion protein combining hELG1 and either Green Fluorescent Protein (GFP) or Cyan Fluorescent Protein (CFP). It has been shown that the fluorescent hELG1 is an excellent reporter for DNA damage within the cell, with increased hELG1 localization to the cell nucleus upon exposure to a genotoxin. Therefore, these cell lines may have utility as a screening tool to detect genotoxic agents.

Available for licensing are the RPE cell line (immortalized normal retinal pigment epithelial cells) stably expressing hELG1-CFP, and the U2OS cell line (human osteosarcoma cells) stably expressing hELG1-GFP.
