Perls Staining for Histochemical Detection of Iron in Plant Samples
[Abstract]  Visualization of iron (Fe) localization in plants has greatly enhanced our understanding of plant Fe homeostasis. One of the relatively simple and yet powerful techniques is the classical Perls blue stain (Perls, 1867). The technique is based on the conversion of ferrocyanide to insoluble crystals of Prussian blue in the presence of Fe3+ under acidic conditions. It has been extensively used in animal and human histology (Meguro et al., 2007) and has recently gained ...
