High Throughput Screening

WuXi Biology offers high-throughput screening (HTS) services in drug discovery to identify new chemical matter. Our experts provide high-quality and cost-effective screening services covering biochemical, radiometric, and cell-based, to high content, multiplex, LC/MS based screening for hit identification and lead discovery.

In addition, we provide compound profiling services. Pharmacology profiling has become an invaluable tool for lead compound selection, optimization and candidate prioritization. Analysis of profile data identifies off-target interactions that can help predict potential side-effects, efficacy and safety of compounds under development before they progress to the more costly stages of preclinical and clinical trials. WuXi Biology offers comprehensive profiling services to fit our clients’ drug discovery & development needs.
