Histological Stains

Histology is the study of tissue structure at a microscopic level, connecting tissue structure with its function. 

Histology almost always uses dyes and stains to color tissues before examining them under the microscope. Without staining a tissue sample, structures tend to be difficult or impossible to see. Further, stains and dyes allow scientists to highlight specific key structures, with certain dyes targeting specific molecules or organelles.

During your time at Mount Holyoke, you may find yourself in a position where you want to use histological stains in your research. Follow this page to learn about the history of these dyes and to guide you towards the dye best suited to your sample.
