Hi, I am hoping some one can help me. I have read several papers recently where they have used CTC (5-cyano-2,3,-ditolyl tretazolium chloride) for staining bacteria to acertain if the cells are active. I am very keen to use this method but have been unable to find a source of CTC. I can not find it listed in any catalogue that I have access to here in New Zealand and chemical suppliers have also been unable to track down a supply. Can anybody give the the details of where to get this stain??
