Signal Transduction and Drug Discovery Services

BioAssay Systems has developed a range of high-throughput assays for drug targets. Our lead discovery services include, but are not limited to, hit-to-lead profiling and structure-activity relationship (SAR) studies.

Signal Transduction and Drug Discovery

BioAssay Systems’ signal transduction and drug screening services are for evaluating changes in cell signaling as a result of exposure to test compounds. The services allow the screening of phosphorylation status modulators in important cell signalling pathways. Our examples include but not limited to the following:
We routinely determine the test compound’s reactivity with different cell species, phosphorylation kinetics and the IC50 of activation or inhibition of the cellular pathway. Learn more.
