NTRK IHC

General Information

What to send:

  • Paraffin block from biopsy, resection or cell block 
  • Unstained mounted sections at 4μm on charged slides on Roche TOMO slides. Slides dried at 37°C 
  • A copy of the original Pathology report.

Please note tissue handling, tissue fixation, time between cutting and staining and excessive drying can lead to loss of expression. Fixatives containing alcohol should not be used and use of Bouin’s fixative will preclude testing by FISH methods.

NOTE: if IHC shows positivity, confirmatory testing via RNA extraction will be initiated. For this, we require the block.
