Featured Small Molecule Product Types

Compound Libraries

The Tocriscreen™ range of bioactive compound libraries are collections of small molecules designed for use in assays for target validation, tool compound identification, receptor de-orphanization and assay development. The range includes libraries covering a diverse range of research areas and targets, as well as focused libraries for specific targets and drug repurposing.


Chemogenetic compounds, such as DREADD ligands and PSEMs, act at genetically modified GPCRs and ion channels, respectively. They enable control of neuronal activity, and investigation of downstream signaling pathways, by initiating a signal cascade from a GPCR or opening of an ion channel pore. 

Fluorescent Probes and Dyes

Fluorescent probes and dyes allow visualization of intracellular structures and individual proteins, and determination of cell types, in live and fixed cells with high sensitivity and selectivity. Our range includes Janelia Fluor® Dyes, cytoskeletal and microtubule probes as well as innovative probes for imaging bacteria.
