My name is Kris Freebairn. I am currently doing a pHD in the department of Genetics at the University of Melbourne, Australia. My research is centred around the mechanisms by which resistance occurs to insecticides in Lucilia cuprina. To do this I am using mutagenesis. So far, I have used EMS which has been quite successful. As EMS has a strong bias towards GC to AT changes, I would like to use another mutagen which can create AT to GC changes. I was wondering if anyone knew of other mutagens which create AT to GC changes at a higher frequency than EMS. I have read that nitrous oxide may create AT to GC changes and GC to AT changes with an equal frequency. Does anyone know if this can be used on flies? Any help would be greatly appreciated. Thanks, Kris. .
