These pages contain protocols for performing wholemount fluorescent in situs. Instructions for two-color FISH and for a combination of fluorescent and colorimetric in situs we have called FCIS. Data can be imaged with a fluorescence stereoscope or a confocal.

  • FISH protocol
  • Fluorescein tyramide synthesis
  • Cy3 tyramide synthesis
  • FCIS protocol

FISH is not as sensitive as standard BM purple in situs, so if you have a very low abundance message it may not be detectable via fluorescence. You can however do a normal purple development for your low expression gene and a fluorescent counterstain- then overlay them to generate a FCIS image. These are both pretty and very good at highlighting quite subtle overlap
