“Staining is the Best Policy”. Visualization in the work of Paul Ehrlich. For nearly all of his life, the biomedical scientist Paul Ehrlich dedicated himself to work on dyes and staining at the interface between so‐called color‐chemistry and histopathology. The article begins by sketching out the field of histopathology at the junction of pathological anatomy, microtechniques, and the development...
We present a color segmentation approach based on a two-dimensional color map derived from the input image. Pathologists stain tissue biopsies with various colored dyes to see the expression of biomarkers. In these images, because of color variation due to inconsistencies in experimental procedures and lighting conditions, the segmentation used to analyze biological features is usually ad-hoc. Many...
A novel fluorescence‐based differential staining procedure has been developed for the rapid visualization of Fusarium pseudograminearum hyphae in cereal tissues. Infected tissues are stained with safranin, which binds to host cell walls, while hyphal tissues are stained with the fluorescent dye solophenyl flavine 7GFE. The method is rapid, does not require clearing of culm cross‐sections, and provides...
