[Drosophila] Re: homemade / cheap GFP/DsRed detection

Howard, can you be more specific about your assay and your budget? Will 
both eGFP and dsRed be in the same animal? Would a set up that shows 
eGFP and dsRed simultaneously be okay?  In what tissue(s) of the fly 
will you expect to see expression? How bright is the expression you 
expect to see? Will this assay be performed in the dark, room light, or 
sunlight? How many dissecting scopes do you need to use for this at one 
time, and what is your total budget for all of them?

There are different possible light sources and different types 
(qualities) of filters, so the info requested will help me (and others) 
make useful suggestions.

I work with whole-body expression of both GFP and DsRed in Drosophila, using it as an individual-level marker in fitness assays. This means I only need to know whether the fly is expressing it or not (as opposed to quantitative differences in expression level or localization). I can’t afford to outfit multiple scopes commercially for a very large assay we have coming. I have found several online resources for building your own detection system, or even simply using a laser pointer, all in worms. Has anyone done this in Drosophila? I'd love know and hear any tips.
