Materials

Tissue Sample

5µ paraffin sections of neutral buffered formalin fixed tissue are suitable.


Protocol

  1. Bring sections to water via xylene and ethanol.
  2. Stain nuclei with alum hematoxylin.
  3. Rinse well with water.
  4. Stain with thioflavine T solution for 5 minutes.
  5. Blot, rinse well with absolute ethanol.
  6. Mount in a fluorescence free resinous mounting medium.

Expected Results

Using a UG1 or UG2 exciter filter and a UV barrier filter, or a BG12 exciter and an OG4 or OG5 barrier filter, amyloid fluoresces lime green or blue.

Safety Note

Prior to handling any chemical, consult the Safety Data Sheet (SDS) for proper handling and safety precautions.
