Advanced Flow Cytometry Applications for Antibody, Small Molecule and Phenotypic Screening


Screening is a cornerstone of drug discovery. Multiplexed, multiparameter screening assays are foundational to the drug discovery process. By collecting more information, researchers may have more confidence in therapeutic candidates as they progress through the discovery and development process.

Flow cytometry is a powerful analytical tool with many applications including antibody and small molecule screening, and cell phenotyping. However, integration of traditional flow cytometry into workflows can be quite complex, this complexity can slow the pace of discovery.

The iQue® Advanced High Throughput Flow Cytometry Platform, represents a powerful and versatile alternative, designed to offer advanced assay capabilities, with the ease-of-use and cost effectiveness sought by research laboratories. Multiplexed, high-throughput measurement of cell-specific parameters, protein analysis, immunophenotyping, functional assessments and profiling, including antibody screening and immune cell activation, deliver breakthrough biological insights with unprecedented speed.

Hence regardless of the application, the iQue® Platform will accelerate and streamline flow cytometry workflows, even for those who are not experts in the use of flow cytometry, delivering actionable results in a decreased timeframe.

This review summarizes recent peer-reviewed publications describing use of the iQue® Advanced Flow Cytometry Platform for antibody, phenotypic, and small molecule screening, as well as novel applications such as extracellular vesicles and siRNA delivery system screening.
