Abstract

An innovative and automated method for the at‐line monitoring of secreted protein was developed by harnessing a Surface Plasmon Resonance‐based biosensor to a bioreactor. The proof of concept was performed by following at‐line the relative concentration of a secreted protein produced by transient transfection of mammalian cells in a bioreactor. Our results suggest that our approach can be readily applied to the at‐line determination of both protein concentration and bioactivity. Our experimental setup and strategy can thus satisfy the needs related to the development of novel bioprocess control protocols in the context of the new process analytical technology that arises in the biopharmaceutical industry.

## Abstract During the last years native chemical ligation (NCL) gained in popularity as a method allowing the chemical synthesis of large peptides and entire proteins. NCL is particularly well‐suited for chemoselective and nondenaturing attachment of biomolecules on solid substrates. In the presen

The performance of immunodiagnostic assays such as ELISA is governed by many different factors. Reflectometry was used to monitor peptide adsorption and the resulting antibody binding activity on a polystyrene surface. Surface plasmon resonance was used to analyze affinity and kinetic parameters of
