Application: Screening FISH-Labeled Planarian (Schmidtea mediterranea)

 

FISH (fluorescence in situ hybridization) is routinely used to label features in planaria (Schmidtea mediterranea). The NIGHTSEA Model SFA Stereo Microscope Fluorescence Adapter can be added to just about any existing stereo microscope to create a practical system for screening samples for successful preparation prior to moving to higher resolution imaging techniques.

All images below made with a conventional stereo microscope fitted with the Model SFA.
