So with this information of how to get the DNA in and stable... now it
seems like the luminescence or fluorescence system needs to be focused
on.... getting enough precursors so the light is bright enough. Can
heat shock proteins repress enzymes, or only gene expression? (i.e.
the light system is present but not functional, then when they're heat
shocked the enzymes go to work chewing up all the built-up reagent)
