Biologics Characterization Tools
Industry Standards for Screening, Characterizing Biomolecular Interactions (Including Antibodies)
The Octet® platform is a comprehensive solution for screening and characterizing molecular interactions such as protein-protein or protein-drug, enabling an enviable variety of applications throughout biologics development from early selection to validation to manufacturing.
Our instruments utilize industry-leading, label-free technologies - Bio-Layer Interferometry (BLI) and Surface Plasmon Resonance (SPR). Both are deemed appropriate for bioanalysis within chapters of the United States Pharmacopeia (USP).
The Octet® family of instruments has been an industry standard for label-free analysis across biologics development and manufacturing for more than 15 years.

Features of the Octet® Platform
Label-free assays measure molecular binding through real-time protein interactions. It is a precise and efficient means of collecting a wide range of information related to affinity, kinetics, concentration, thermodynamics, bio-similarity, specificity, potency and selectivity of molecular binding.
Octet® is a powerful platform designed to understand structure-function relationships between molecules, and it can be applied at many different stages throughout the drug development process.
Octet® BLI assays are ideal for titer and concentration analysis as well as screening for Critical Quality Attributes (CQAs) early in cell line development and bioprocess development workflows.
On the other hand, Octet® SPR’s next-generation SPR technology simplifies kinetic characterizations and fragment screens.
Label-free BLI and SPR are used from screening (at the very early stages of drug discovery) to identifying and engineering potential binding candidates, supporting clinical evaluation and finally during quality control(QC) of GMP manufacturing.
Over the last two decades, these systems have been upgraded to show significant improvements in sensitivity and software capabilities, leading to higher workflow efficiencies and more unlocked applications.
