Instrumentations

Compound screening against a drug target whether by high-throughput screening or fragment screening is a vital step in early stage drug discovery. Biortus has an extensive collection of plate readers (detecting UV/light absorbance, fluorescence, luminescence, and scintillation) that allows development of many kinds of biochemical assays including cell-based assays. Coupled with our automated liquid handling machines, we could perform various high-throughput screening (HTS) for our clients. In addition, Biortus currently holds two other specialised screening technologies, Mobility Shift Assays (Caliper EZ Reader II, great for monitoring enzyme reactions) and Surface Plasmon Resonance (SPR, Biacore S200) for fragment screening. Below is a non-exhaustive list of assays performed in Biortus:
