4micron Paraffin wax sections


SOLUTIONS

  1. Alcian Blue pH 3.1
    • Alcian Blue 1g
    • 0.5% Acetic Acid 100ml

  2. Alcian Blue pH 2.5
    • Alcian Blue 1g
    • 3% Acetic Acid 100ml

    • Distilled water 100ml


METHOD

  1. Take sections to water
  2. Stain in alcian blue solution pH 2.5 for 5 minutes
  3. Wash well in water
  4. Counterstain in 0.1% nuclear fast red for 5 minutes
  5. Wash in water
  6. Dehydrate, clear . Mount sections in DPX

  • Mucins - Bright Blue
  • Nuclei - Red


NOTES

  1. To further identify specific types of acid mucins you need to use the other pH solutions.

    • Strongly sulphated mucins - use pH 0.2 Alcian Blue
    • Weakly sulphated mucins - use pH 2.5 or pH 1.0 Alcian Blue

  2. When using low pH solutions drain and blot dry instead of washing at stage (3) of the method.
