Toluidine blue is a basic thiazide metachromatic dye with high affinity for acidic tissue components, so Stain DNA and RNA-Rich Tissues. Because of its metachromaticity, it has been widely used for important and special staining in living tissue.

Does toluidine blue stain bacteria?

Bacteria are more easily detected in broth cultures If preparations were stained with 0.5% w/v toluidine blue instead of by Gram staining technique.

What is the mechanism of action of toluidine blue dye in the early detection of oral cancer?

(Figure 1) Toluidine blue is a metachromatic dye when used for histological analysis.A clinical mechanism of action appears to be Dye has greater penetration and temporary retention in the intercellular space of rapidly dividing cancer cells in vivo.

Why are neuronal bodies stained blue with toluidine blue?

Cobalt sulfide (Chapter 19) was precipitated with ammonium sulfide and washed extensively with saline solution prior to toluidine blue staining.Since ammonium sulfide is a reducing agent, the staining is initially discolored and the cell body is only blue during fixation and dehydration.
