In drug discovery screening campaigns as well as in fundamental research activities, cellular parameters have to be measured and monitored in living cells regularly. Often fluorescent dyes are used to detect and follow some of the parameters. These methods are powerful, especially in screening large numbers of compounds, but have their limitations e.g. when it comes to measuring more than one parameter in the same living cell, or when specific locations in the cell shall be targeted.
To overcome these limitations and to provide tools to especially look into GPCR related signalling in the most comprehensive and detailed way currently possible, Montana Molecular have developed genetically encoded fluorescent biosensors to measure parameters such as cAMP, DAG, PIP2, Ca2+and voltage changes in living cells.
