We Are ION Biosciences

We build innovative, fluorescence-based tools for scientists across all fields of cell-based research, with a primary focus on drug discovery for ion channels, ion transporters, and GPCRs.

Fluorescent Indicators

We offer a collection of membrane permeable and impermeable ion indicators for calcium, sodium, potassium, and thallium, as well as other fluorescent dyes to meet your research needs. Our indicators are rigorously validated so you can have confidence in your results. 

We combine our best fluorescent indicators with other critical reagents, rigorously validated protocols, and detailed, easy-to-follow instructions to provide industry-leading assays that outperform the competition and accelerate your research.

Custom Services

Our expertise in early stages of integrated drug discovery – hit identification, hit-to-lead, and lead optimization – combines fluorescence-based assays that we invented with advanced tools for rapid data acquisition and reporting. Our collection of services includes ion channel and GPCR-focused assay development, high-throughput screening, cell engineering, cell-based assays, and more.
