Product summary

  • Technology FISH
  • Application Solid tumour
  • Product Code LPS 100
  • Regulatory Status For use in heat pretreatment and enzyme digestion of Formalin-Fixed, Paraffin Embedded (FFPE) tissue prior to Fluorescence in situ Hybridisation (FISH) or Chromogenic in situ Hybridisation (CISH) detection. This product is intended for general laboratory use or use in a Laboratory Developed Test (LDT). If used as part of an LDT, it is the responsibility of the laboratory developing the test to validate the test before use in a clinical setting.


Introducing the first Pretreatment kit capable of preparing slides for CISH and/or FISH analysis on Formalin-Fixed, Paraffin-Embedded (FFPE) tissue.

Our ready-to-use Tissue Pretreatment Kit has been optimised to produce excellent visual results with our extensive CytoCell® Pathology FISH range.

To further extend the utility of the kit we have also validated its use with other commercially available CISH (chromogenic in situ hybridisation) and FISH (fluorescence in situ hybridisation) DNA probes*.

With ease-of-use and convenience in mind, our simple two stage FFPE slide preparation protocol employs the use of ready-to-use reagents; which have been optimised to increase the permeabilisation of cell membranes and facilitate penetration of the desired FISH or CISH DNA probe.
