Fluorescent Probes

Essential tools for life science research

Fluorescent probes bound to receptors or proteins enable researchers to detect particular components of complex biomolecular assemblies, such as live cells, with high sensitivity and selectivity. Tocris also offers a wide selection of fluorescent dyes, labels and stains.
