How Low Can You Go? A New Era of Sensitivity in Octet® BLI,  Application Note

Last updated: October 20, 2025

Resource overview

Assay sensitivity in biomolecular research and drug discovery plays a pivotal role in determining whether an assay or technique can be used, particularly in early pipeline applications. Additionally, sensitivity contributes to the precision and accuracy of measurements. It enables the differentiation between specific and non-specific binding (NSB), reducing background noise and enhancing the signal-to-noise ratio. This precision is essential for obtaining reliable kinetic data and understanding the mechanistic aspects of interactions.

The Octet® R8e BLI system represents a breakthrough in label-free interaction analysis. More than just an upgrade, it signifies a true evolution of BLI technology, offering unparalleled sensitivity that empowers researchers to detect and quantify analytes even at low abundance levels. This document serves as a comprehensive guide, showcasing best practices for generating high-quality data across a diverse array of compounds and molecular weights.
