Hitchcock Ehrich
for Plasma Cells

This method uses malachite green and acridine red to stain plasma cells in a similar manner to the methyl green pyronin methods.


Solution A
Malachite green 1 g
Distilled water 100 mL
Solution B
Acridine red 3 g
Distilled water 100 mL

Combine 1 part of solution A with 3 parts of solution B immediately before use.

Tissue sample
Zenker fixation is recommended. Other fixatives may not be satisfactory.


  1. Bring sections to water via xylene and ethanol.
  2. Place into the staining solution for 30 seconds.
  3. Rinse with water.
  4. Dehydrate rapidly with absolute ethanol.
