In the eFISH procedure, fixed tissue sections are pretreated to expose target DNA or miRNA sequences. An appropriately labeled probe is hybridized to the exposed target DNA or miRNA sequences in the cells. Subsequent stringent washing steps remove any probe that is non-specifically bound to the tissue section. Subsequently slides are mounted using DAPI/antifade and can be visualized under fluorescence microscope using appropriate filter set. BioGenex provides a whole catalog of eFISH probes as well as automated systems.
