High Throughput Screening (HTS) is a drug discovery process that allows automated detection of large numbers of chemical and/or biological compounds for a specific biological target. It speed up target analysis, as large scale compound libraries can be quickly screened in a cost-effective way. HTS should be seen as a fast scan of biological processes by which compounds with poor or no effects can be rapidly excluded from the analysis pipeline.

Creative Bioarray is a full-time, professionally managed facility with highly trained and experienced staff, advanced equipment, and a substantial library of compounds. These features, combined with a centralized knowledge base, increase cost-effectiveness and productivity in the ongoing fight against disease. Our platform allows convenient screening of compounds in 96, 384 and 1536 well formats for both enzyme/protein and cell-based assays using all available technologies (luminescence, fluorescence intensity, fluorescence polarization, FRET, TR-FRET, HTRF, absorbance). We have developed and optimized in vitro enzymatic assays, protein binding assays, protein-protein, protein-nucleic acids binding assays, cell viability, reporter gene and image-based phenotypic screening assays.

Technical Infrastructure

Our platform is equipped with instrumentation, robotic automation, and software for running high-throughput screening using a variety of assay technologies. The infrastructure is highly flexible, making it possible to run assays at any size.

  • Automation - A variety of liquid handling and robotic platforms make it possible to perform assays accurately and efficiently at any scale.
  • Detection devices - Numerous multi-label plate readers enable a wide range of plate-based assays.
  • High throughput microscopy - High-quality image analysis software are combined with high throughput automation technologies for results analysis.
  • Screening libraries - We use an extensive catalog of small molecules for molecular screening.
  • Informatics - Provide advanced analytics by using various software applications.

Creative Bioarray also offers compound screening services for client libraries in a single compound format or compressed format, and store copies of your library for multiple screening campaigns. With our extensive experience in medicinal chemistry, we are able to promote drug discovery programs into development and clinical trial stage efficiently and cost-effectively.
