Inspiralis provides researchers involved in drug development with the necessary tools to develop and screen novel compounds particularly in the anti-infective and anti-cancer areas. Specialising in DNA-modifying proteins, we have been supplying products and services since 1995 including topoisomerases, helicase and ligases. We provide enzymes, substrates and assay kits as well as a range of services including compound screening, determination of their mechanism of action, cloning and expression of mutants, and some structural studies.
