🔬 What Is the Quick III Kit?

The Quick III Kit includes:

  • Quick III Fixative – Preserves cellular structure.
  • Quick III Solution I (Eosin) – Stains cytoplasmic components.
  • Quick III Solution II (Thiazine) – Highlights nuclei and microbial organisms.

These ready-to-use, certified dyes are designed for rapid staining, delivering results comparable to Wright-Giemsa protocols in under a minute.

🧬 Procedure : Histology – Paraffin-Embedded Slides

This method demonstrates H. pylori presence in tissue biopsies using paraffin-embedded slides.

Step-by-Step Instructions

  1. Deparaffinization
     Pass the slide through xylene, then graded alcohols, ending in distilled water.
  2. Solution I (Orange – Eosin)
     Place the slide in Solution I for 1 minute.
  3. Solution II (Blue – Thiazine)
     Transfer directly into Solution II for 1 minute.
  4. Quick Rinse
     Rinse gently to remove excess stain.
  5. Acetic Acid Dip
     Briefly dip in 0.25% acetic acid to enhance differentiation.
  6. Alcohol Differentiation
     Pass through 95% alcohol, then absolute alcohols.

Clearing & Mounting
 Clear in xylene, then apply a coverslip as usual.
