| A device for the characterisation of microorganisms comprising a porous body having regions of differing pore size said regions being associated with different chromogens specific to enzymes produced by microorganisms. |
| The excellent contrast between the Fast Red and DAB chromogens allows for easy antigen differentiation. |
| Solubilized phthalocyanine reactive dyes are used for bright turquoise shades that cannot be obtained with either azo or anthraquinone chromogens. |
| Without substituents, chromophores do not absorb visible light, but the auxochromes shift the absorption of these chromogens into the visible region. |
