One of the most powerful techniques in molecular biology is the controlled
expression of specific proteins by transfection of eukaryotic cells. This m
ethod has become feasible and highly sensitive and, thus, suitable for high
-throughput reporter gene assays in basic and applied research. Moreover; t
he limiting factors are neither the transfection efficiency nor the functio
nal analysis, but rather the ability to manage complex experimental protoco
ls when multiple genes are co-transfected and/or when the effects of severa
l chemical compounds are investigated within the same experiment. Here, we
describe an easy-to-use and highly flexible spreadsheet template intended t
o rationalize and expedite the organization and data management of multi-st
ep reporter gene assays. The objectives of this spreadsheet template are th
e design of the transfection protocol, the coordination of the administrati
on of test compounds, and the graphical presentation and statistical analys
is of the results.
