Techniques for monitoring cell cultures and fermentation processes not only enable prompt feedback to variations in critical parameters (e.g., media composition and metabolites) but further improve our understanding of the processes themselves. In this context, surface plasmon resonance (SPR) spectroscopy is one of the methods of choice. This technique(More)
We used the interaction between human serum albumin (HSA) and a high-affinity antibody to evaluate binding affinity measurements by the bench-top liSPR system (capitalis technology GmbH). HSA was immobilized directly onto a carboxylated sensor layer, and the mechanism of interaction between the antibody and HSA was investigated. The bivalence and(More)
Continuously monitoring cell cultures is essential for both controlling critical parameters and improving understanding of key processes. An ideal technique in this context is surface plasmon resonance (SPR) spectroscopy, which essentially exploits changes in the angle of incident light that occur when molecules bind to a surface. It provides the ability to(More)
