Specialist Ion Channel Screening
Accelerate early-stage screening and lead optimisation
Ion channel Screening services by ion channel experts
We understand the importance of robust, reliable assays in enabling you to make timely, well-informed decisions. Using innovative solutions tailored to your specific target, we focus on rapid delivery of high-quality data to accelerate your early-stage compound screening and lead optimisation programmes.
Our specialist team of ion channel scientists are experts in their field. With over 250 years’ collective ion channel drug discovery experience, we specialise in developing, optimising and validating high-quality ion channel screening services using a range of electrophysiology and fluorescence-based platforms.
We fully customise ion channel assays at different stages of the screening cascade, from high-throughput screening (HTS) and structure-activity relationship (SAR) studies, through to specialised biophysical and mechanism-of-action studies for lead compounds.
