Virtual Method Optimization and Size Analysis for FFF
September 11, 2017
- Flow-field flow fractionation (flow-FFF) offers highly versatile separations for the analysis of complex fluids, covering a size range of macromolecules and particles from 1 nm to 10,000 nm. However, flow-FFF is often perceived as a difficult technique to learn because of the multiple parameters available for adjustment.
Our new SCOUT DPS® software simulates flow-FFF from basic physical principles, enabling the virtual optimization of flow-FFF methods and opening up the power of flow-FFF separations to non-experts. SCOUT DPS also analyzes particle size distributions (hydrodynamic radius) by elution time to increase characterization capabilities. This publication in The Column explains how it works.

Drug discovery: Finding, then losing, then finding again colloidal aggregates of small-molecule drugs with DLS
July 1, 2017
- Dynamic light scattering is not just for proteins and nanoparticles. In the field of small-molecule drug discovery, high-throughput DLS with the DynaPro Plate Reader II has at least one key role - preventing the accumulation of misleading hits, or false positives, that are a result of aggregated compounds. Brian Shoichet's UCSF lab has been instrumental in elucidating the mechanism of action and prevention of these promiscuous inhibitors, utilizing the DynaPro PRII for detection and formulation. Read highlights of his publications and a link to a recent online interview.

Protein Quality Control in SPR and BLI High-Throughput Screening Studies
May 9, 2017
- Protein-protein binding studies are only as good as the quality of the reagents used in the experiments. Great resources in terms of instrumentation, sample production and scientist time are typically invested in high-throughput screening of antibodies or fragments to obtain optimal therapeutic candidates, perform epitope binning and rank candidates by affinity and kinetics. However, often little attention is paid to verifying protein solution quality—which can lead researchers down the proverbial rabbit hole, chasing after ephemeral or anomalous results that are caused by degraded proteins. To download a white paper describing a fast, easy and non-perturbing pre-screening method using the DynaPro Plate Reader II, click here.
