chemical reactions reaction with Melzer's reagent presence

Very important and differentiating reactions! Reactions should always be observed with normal light at the highest magnification. An interference contrast can obscure positive reactions, therefore normal bright field microscopy should be applied. Sometimes only a very slight bluing can be detected. On brown hyphae these reactions are mostly difficult to be observed, if possible at all. Be sure that you do not misinterpret a blue colouration of stained starch granules as positive. Melzer's reagent should not be older than one year!
