  • Title: A study of the mechanism of the toluidine blue dye test.
    Author: Herlin P, Marnay J, Jacob JH, Ollivier JM, Mandard AM.
    Journal: Endoscopy; 1983 Jan; 15(1):4-7. PubMed ID: 6185331.
    Abstract:
    Toluidine blue is commonly used by endoscopists as a screening test for squamous cell carcinoma. Little information is available on the mechanism of vital staining as it is not preserved by conventional fixation. By using a simple method to stabilize toluidine blue, the authors were able to study the action of the dye under the light and electron microscope. The findings are reported.
