TopoGEN Screening Services

TopoGEN offers a custom screening program that utilizes the kits, enzymes, and reagents we have developed and that our customers have used with success over the past 20 years. Now you can shorten your project timeline and commit our staff of experts to your compound screening pursuits. We can accomplish in days what may take weeks or months for other labs. You simply provide us with your compounds in either a dry or stabilized state at a known concentration or weight. We offer three levels of custom services for topoisomerase I, II, IV, E. coli DNA Gyrase and S. aureus DNA Gyrase. In most cases, the customer knows whether an inhibitor vs. poison is associated with the compound to be tested. This makes custom screening cost effective since it narrows the screening process.

All screening contracts conclude with a final technical write-up reviewed and signed by our President and CEO, with an option for follow-up evaluations by our scientists if necessary.
