Description

Chromotrope 2R is a chromogenic substrate that is used to assay protothecosis. Phase chromatography of this compound produces two different zones: one that is blue and another that is yellow-green. The blue zone indicates the presence of phosphotungstic acid, which can be used as a diagnostic marker for protothecosis. The yellow-green zone indicates the presence of keratinization, which can be used as a diagnostic marker for protothecosis. Chromotrope 2R has also been shown to inhibit keratinization in tissues, leading to a lack of staining and cellular changes in the surrounding tissue.
Prototheca species are filamentous eukaryotic organisms that produce a variety of polyketides and other secondary metabolites. These compounds are toxic to animals when ingested and can lead to hemorrhagic necrosis in both humans and animals. Protothecosis is caused by infection with Prototheca zopfii or Prototheca w
