TG1017
This kit is designed to allow the customer to screen for agents (drugs, natural products, small molecules, synthetics) that block the catalytic activity of human topoisomerase I (topo I).  The use of high stoichiometric ratios of topo I:DNA induces cleavage complexes without the need to use topo I poisons…

TG1019
This kDNA based Topo II Drug Screening Kit is designed to identify agents that target type II topoisomerases acting as catalytic inhibitors, primarily; however, poisons can also be detected with this kit.
TG1018
The Topo I Drug Kit is designed to allow the investigator to quickly identify novel inhibitors of Human Top1.  The kit will allow detection of novel compounds that either stabilize the nicked intermediate or otherwise inhibit catalytic activity of topoisomerase I.  
TG1009
This is a cleavage based detection kit that will reveal whether a particular agent either antagonizes the action of topo II or affects the cleavage/religation cycle.  Reactions are assembled in microcentrifuge tubes using reagents supplied in the kit (buffer, DNA, control inhibitor).
TG1007
The Topoisomerase IV Drug Screening Kit contains reagents necessary to identify compounds that affect enzyme activity.  Note that kits with a catalog number denoted -A will include E. coli topoisomerase IV enyzme.    
TG4039
Proteinase K is a subtilisin-like endolytic protease that is isolated from the saprophytic fungus Tritirachium album.  It has a high activity that is stable across a wide range of pH and temperature conditions and is suited to short digestion times.  The activity of proteinase K is increased at…

TG4037
Is used to terminate topoisomerase reactions.  To terminate reactions, add 1/5 volume to the reaction prior to loading agarose gel.      
TG4090
Topo II Dilution Buffer is supplied as a working solution at 1X solution.  The buffer is optimized and tested for use as a diluent for TopoGEN’s type II topoisomerase.        
TG4060
High purity SDS is dissolved in triple glass distilled/deionized, sterile water to 10% (w/v).  The ability of each lot to function as an effective topoisomerase denaturant is tested and verified for each lot.  
TG4045
S. Aureus Gyrase Assay Buffer (1ml).
