Who We Are
StainsFile is an online resource for researchers and histopathologists looking to visualize their cells. From the theory and basics of cell staining to protocols for building an end-to-end workflow for staining experiments, StainsFile covers tissue processing, reagent preparation, staining, and post-staining treatments to support proper visualization of cells and cell structures.
StainsFile was originally created by Bryan D. Llewellyn, a biomedical scientist who supervised the Histopathology Laboratory at Prince George Hospital in the Northern Interior of British Columbia, Canada, for 26 years. Bryan was fascinated by understanding why dyes stain tissues, and how the process can be controlled. As he studied the subject, he often had difficulty finding an explanation of why a particular procedure worked. It was this scarcity of information that motivated Bryan to launch the original StainsFile website. He continued to add to the site for many years, ultimately amassing hundreds of protocols and reference pages for scientists performing histopathological techniques. Bryan retired in Ladysmith, British Columbia, on Vancouver Island.
