Cryosection troubleshooting
WebUse low pH solution such as citrate buffer (pH6.0) antigen retrieval Solution to replace EDTA (pH8.0) or Tris-EDTA (pH9.0) retrieval solution if it is possible. Distilled water alone may make sections come off slides easy. Always use buffer solution to wash or rinse slides. Bone (especially the cartilage) tends to fall off slides after HIER. WebMove the embedded tissue directly into the cryostat and use OCT medium to mount it to the chuck. Allow the temperature of the tissue to equilibrate with the cryostat. Cut the tissue in 5-20 µm thick sections. Mount tissue sections onto gelatin or poly-L-lysine coated slides by placing the cold sections onto warm slides.
