Hi DK, you mean this: https://secure.wikimedia.org/wikipedia/en/wiki/Fluorescein "ordinary" Fluorescin?
Yes, it was my first thought, as you may get it quite cheaply in technical quality, even through eBay. I dismissed it quite fast, as I had mad "bad" experience with FITC as label in fluorescence microscopy - too fast bleaching, when irradiating with blue light from a mercury lamp or even 488nm laser. As for now, the main purpose would be tracing an organic compund / labelled protein during processing, am I overconcerned maybe? Thanls, Wo > > Carboxyfluorescein? Not sure about price.
