Project Goal

To accomplish our customers' small molecule and biologics characterization tasks in a cost-effective and resource-efficient manner, while maintaining the highest data quality DCs) in terms of amino acid sequence, drug-to-antibody ratio (DAR) and post-translational modifications.

The Challenges

  • Ever-evolving therapeutic concepts and modalities require constant analytical method innovation
  • Enormous expertise required to develop and validate bioassays for different compound classes
  • Multiple software pieces are often required for data analysis and reporting, which is costly to maintain

The solution

  • Robust and versatile LC-MS platform to allow small molecule assays, as well as biologics workflows
  • Multiple-attribute methodologies (MAM) offer streamlined single methods to complement or replace multiple assays needed for biologics product characterization and process control
  • Fully integrated solution and unified user interface from SCIEX OS Software and BPV Flex Software that allow easy implementation

The outcome

  • Quickly develop and execute small molecule and biologics characterization assays
  • Client's ability to quickly iterate through various experimental conditions and make evidence-based decisions
  • "The ease of use and intuitiveness of SCIEX OS Software is absolutely delightful"


A contract research organization (CRO) that specializes in epigenetic modification profiling as well as contract analytical development.
