(A) Images of tumor load as indicated by luciferase activity. Traditionally, human toxicant bioavailability screening has been forced to proceed in either a high throughput fashion using prokaryotic or lower eukaryotic targets with minimal applicability to humans, or in a more expensive, lower throughput manner that uses fluorescent or bioluminescent human cells to directly provide human bioavailability data. Today, bioluminescence from Aliivibrio fischeri is used to monitor water toxicity. It can be synthetically made and is an ingredient in all of the vaccines if you dig deep enough.
