The mice were also regularly injected with luciferin , so that the luciferase would have the fuel it needed to glow .
老鼠还被定期注射荧光素，这样荧光素酶就有足够的原料来发光。
Unlike jellyfish photoproteins , which require calcium to light up , luciferase from fireflies needs a ready supply of luciferin and atp .
不像水母的发光蛋白需要钙离子来激活发光，萤火虫体内的荧光素酶需要足够的荧光素和atp供应。
Instead of having freely available luciferin , they contain molecules called photoproteins which are , in effect , luciferin proteins that already have oxygen bound to them .
