A New Ultra Sensitivity Approach for Protein Quantitation

John and Dom introduce guest Brad Nawa (Alamar Biosciences) to explain the NULISA™ platform, an ultra-sensitive platform for protein quantitation that aims to outperform earlier “ultra-sensitive” tools that often didn’t translate well in practice. Brad notes the platform is still antibody/content-driven, but differentiates itself by reducing background through a dual-capture purification step and a nucleic-acid barcode/ligation readout, enabling scalable multiplexing (currently ~256-plex, with room to expand). They emphasize the fully automated ARGO™ HT system as a key advantage for minimizing operator variability and supporting strong instrument-to-instrument and lot-to-lot reproducibility. The discussion covers applications including biomarker discovery/monitoring, patient stratification, and PK/PD - especially when sample volume is limited or sensitivity is critical - and use across many matrices (plasma/serum/CSF, tissue lysates, vitreous humor, and dried blood/plasma spots with high recovery reported for most targets). They close by framing the future around building robust datasets for AI/meta-analysis, expanding therapeutic content (notably CNS/neurodegeneration, immunology, and cardiometabolic), and improving cloud software for pathway-level interpretation.“The Weekly Bioanalysis” is a podcast dedicated to discussing bioanalytical news, tools and services related to the pharmaceutical, biopharmaceutical and biomarker industries.
