The first phase was described as a proof of concept/principle. The cost of the other phases would likely be more per phase than just testing to check feasibility, so I'd wager that it takes $500k or more for the remaining phases. Otherwise, why seek $3 million for what they described as development, expansion and marketing? They had mentioned $2 million a few years back for expansion and if that's still the number for that, then that leaves a million for development and marketing. I believe this pretest N-Assay could make the whole corporate technology package attractive to other players in the diagnostic sphere. Just my thoughts.
