The assembled HARPOON kit:

dish set up

The dish setup goes inside of the box. The UV flashlights in the side of the box will shine upon the glass plate and mesh screen.  The illuminated mesh screen should be viewable through a filtered hole in the top of the box. Every 30 seconds for 10 minutes, a photo of the screen will be taken with a cellphone camera positioned on top of the hole.


Data processing:

Students will  upload their photos to a computer and use the public-domain image processing software, ImageJ, to process the data. The image processing steps have been mostly automated by the development of Java code macros. In the final step, assay activities are mapped onto compositional diagrams to reveal promising “hits.”
