Biochemical Kinase Assays | Thermo Fisher Scientific

Thermo Fisher Scientific offers you the broadest set of biochemical fluorescent assays to address high-throughput screening, hit confirmation and lead optimization programs. All Invitrogen kinase assay technologies are homogenous, non-radioactive, and highly miniaturizable – and are available as kits, custom or bulk reagents.

To compile the components needed to make the right biochemical kinase assay for your research, use our new Drug Discovery Assay Maker web tool.
