INTRODUCTION

In Situ Hybridization (ISH) is a powerful technique for localizing specific nucleic acid targets within fixed tissues and cells, allowing you to obtain temporal and spatial information about gene expression and genetic loci.

ISH detection kits are designed by Chromogenic In Situ Hybridization (CISH) in formalin-fixed, paraffin-embedded tissue sections, cell samples, blood or bone marrow smears, and metaphase chromosome spreads.

ADVANTAGES OF CISH OVER FISH

  • Quick and easy interpretation of results comparable to IHC
  • Simultaneous observation of tissue morphology and CISH signals
  • Storage of slides at room temperature – CISH signals are permanent
  • No costly fluorescent microscope needed.
