Cloning and expression of mutants

Although we have topoisomerases from a number of organisms as well as a range of mutants, if the protein of interest to you does not seem to be available then we should be able to make it for you.  If you tell us which protein you are interested in then we can clone the subunits, express and purify them and supply you with a characterised product.

If you are interested in a particular mutant of a protein we have and it does not seem to be available on our list then please enquire, we may have it available and if not we can make it for you. 

We can also provide protein for particular purposes such as X-ray crystallography.
