Master the challenges of cell-based fluorescence assays

By Dr Stefan Haberstock

Cell-based assays are giving us deeper insight into cellular mechanisms in a true biological context, and fluorescence assays are playing a leading role. Applications range from cytotoxicity, proliferation, apoptosis and G-protein-coupled receptor (GPCR) signaling assays to high-throughput screening (HTS) drug discovery.

How to develop an optimal fluorescence assay

By Dr Stefan Haberstock

Fluorescence detection can give you the ability to develop assays with extreme sensitivity, high robustness and a broad dynamic range. Success involves addressing several challenges, such as the careful choice of excitation (Ex) and emission (Em) wavelengths and the selection of flexible and sensitive optics, as we will see here.

A brighter future with fluorescence-based assays

By Dr Stefan Haberstock

Compared to many other detection technologies, fluorescence provides hard-to-beat performance and flexibility. Fluorescent labels are stable for months, deliver high sensitivity and the diversity in available dyes gives nearly unlimited possibilities in assay design. This and many other advantages make implementing fluorescence detection one of the easiest and safest ways for you to improve the quality and sensitivity of your assays.
