Frequent Uses

Hematoxylin Differentiation 

Used for aggressive removal of excess hematoxylin or decolorisation during regressive H&E workflows. This stronger formulation is effective in protocols where standard differentiation may be insufficient or where restaining is needed.

Acid‑Fast Staining (e.g. Ziehl‑Neelsen, Kinyoun)

Acts as the decoloriser in acid‑fast protocols, removing non‑acid‑fast dyes while retaining carbol fuchsin in target organisms. Ideal for Ziehl‑Neelsen and modified Kinyoun staining.
