To accelerate commercialization of biotherapeutics, organizations need to optimize processes by integrating advanced analytical tools that maximize quality, safety, and efficacy. Octet® BLI systems enable real-time, label-free analysis for the determination of kinetics, affinity, and antibody/protein quantitation. Based on Bio-Layer Interferometry (BLI), the systems enable an enviable variety of applications throughout biologics development, from early selection to validation and manufacturing. Read on to learn about the implementation in the production of biotherapeutics for titer, host cell protein analysis, residual protein detection, sialic acid content detection, potency assay development, Fab activity assay development, and more.
A more streamlined technique with reduced hands-on time using the Octet® platform. For customers who require a sensitive and robust assay for measuring small amounts of leached Protein A in antibody or Fc-fusion protein samples.
Replace ELISA and HPLC with Octet® systems for quantitation of antibodies and recombinant therapeutic proteins. Accurate and fast assays are also easy to develop and transfer to QC and manufacturing. In this whitepaper you will learn about analyzing a full plate (96-samples) of IgG titer in as little as two minutes, assay directly in crude and unpurified samples, and automation for extending un-attended run times and high throughput analysis.
