Using a luciferase gene to measure cellular responses

In the Project, it is important that researchers can measure the effects that a food component has had on a . A from the firefly has been added to the cells. This gene is linked to the pathway in the cells. Dr Martin Philpott from Auckland Medical School uses a luminometer to measure the amount of light that is produced by the cells. This tells him whether a particular food compound has affected the inflammation of the cell.

This machine is a luminometer. It measures luminescence, which is what the that we’ve put into our cells will be expressing. The luciferase gene emits light. It’s the same gene that is present in fireflies and is responsible for the light emitted by fireflies. The machine here, the luminometer, measures each of the wells in those 96 or 384 well plates for the intensity of light that they’re emitting, and therefore for the amount that our luciferase gene has been turned on in response to our food compounds.
