Designing label-free biosensor assays for Fc receptor binding analysis
Understanding Fc gamma receptor (FcγR) binding kinetics is critical for biotherapeutic development. This application note explores label-free biosensor assays using Alto™ Digital SPR™, highlighting best practices for assay optimization, immobilization strategies, and data analysis to enhance antibody characterization.
A novel icIEF fractionation and SPR-based workflow for correlating the charge structure to the function of a bispecific antibody
This application note introduces an innovative icIEF-SPR workflow for characterizing charge heterogeneity in bispecific antibodies. Using the MauriceFlex system for fractionation and the Alto SPR system for binding analysis, this study highlights the critical role of charge variants in therapeutic development.
Characterization of Fc Gamma Receptor and IgG interactions using Alto
Label-free analysis of biomolecular interactions is critical in the development of biologics, but current analytical instruments are not equipped to meet the needs of the modern biologics researchers. They require substantial amounts of sample and years of experience to produce high-quality data. Alto™, Nicoya’s Digital SPR™ platform, solves these problems through the use of digital microfluidics and integrated LSPR sensors. This application note demonstrates the application of Alto for measuring biomolecular interactions and generating data that is comparable to biolayer interferometry (BLI).
Characterization of biomolecular interactions using Alto
Label-free biomolecular interaction analysis is essential for biologics development, but conventional systems often require large sample volumes, skilled personnel, and complex fluidics prone to reliability issues. Nicoya’s Alto overcomes these challenges with digital microfluidics and integrated LSPR sensors, enabling label-free analysis in sub-microliter droplets. This application note shows that Alto delivers kinetic and affinity results matching a traditional SPR platform, using just 1% of the sample and requiring less than 30 minutes of hands-on time, making it a highly efficient, user-friendly tool for biologics discovery.
