Do I need to deparaffinize my paraffin-embedded tissue sections before staining F-actin with Phalloidin-iFluor® conjugates? Can you provide a deparaffinization protocol?

Posted April 2, 2019


Yes, in order to stain F-actin with any fluorescent phalloidin conjugate you must first deparaffinize (remove paraffin) your paraffin-embedded tissue sections. To deparaffinize your tissue section:

  1. Warm slides to 57 °C for 5 minutes.
  2. Immerse sections in 2 changes of xylenes, 5 minutes each.
  3. Immerse sections in 100%, 95%, and then 70% ethanol, 5 minutes each.
  4. Wash 2 times in 1X PBS, 5 minutes each.
  5. Proceed to F-actin labeling procedure.
