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.

Systems
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:
Camptothecin (CPT) class of compounds has been demonstrated to be effective against a broad spectrum of tumors. Their molecular target has been firmly established to be human DNA topoisomerase I (topo I). CPT inhibits topo I by blocking the rejoining step of the cleavage/religation reaction of topo-I, resulting in accumulation of a covalent reaction intermediate, […]
July 20, 2018 TopoGEN was featured in the local press in order to showcase our collaboration with Nanoly Bioscience based out of Boulder. Nanoly has developed a polymer-based cage (the NanoShield) that can protect labile products from fluctuations in temperature and possibly obviate need for expensive dry ice transit around the world. TopoGEN is going to field […]
