Abstract:
In many areas of drug discovery and development, scientists are in a constant search for methods and platforms to reduce assay time and cost. The Gyrolab™ microfluidics platform that we describe here promises to deliver faster ligand-binding assays with lower reagent and sample consumption, while maintaining good accuracy and precision. Due to its limited track record, we evaluated its performance on assays currently used to support pharmacokinetic and immunogenicity studies, and detection of host cell protein impurities in samples from biotechnology processes. This article summarizes our preliminary conclusions about the utility of the Gyrolab microfluidics platform from Gyros AB.

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
