Chloromethylisothiazolinone (CMIT) and 2-methyl-4-isothiazolin-3-one (methylisothiazolinone or MIT) are popular derivatives. A 3:1 mixture of CMIT:MIT is sold as Kathon. Kathon is supplied as a concentrated stock solution containing from 1.5 to 15% of CMIT/MIT. For applications the recommended use level is from 6 ppm to 75 ppm active ...

The pH indicator Methyl Red is added to one tube and a red color appears at pH's lower than 4.2, indicating a positive test (mixed acid fermentation is used). The solution remaining yellow (pH = 6.2 or above) indicates a negative test, meaning the butanediol fermentation is used.
Normally acid dyes would stain the same basic proteins, but by applying them sequentially the staining pattern can be manipulated. A polyacid (such as phosphomolybdic acid or Phosphotungstic acid) is used to remove dye selectively. Polyacids are thought to behave as dyes with a high molecular weight: they displace easily removed dye from collagen.
These enzymes are capable of reducing the tetrazolium dye MTT, which is chemically 3-(4,5-di methyl thiazol-2-yl)-2,5-diphenyltetrazolium bromide, to its insoluble formazan, which has a purple color. Other closely related tetrazolium dyes including XTT, MTS and the WSTs, are used in conjunction with the intermediate electron acceptor, 1-methoxy ...
