On paper, scaling a bioprocess from a 10-L to a 100-L to a 2,000-L bioreactor may seem like a straightforward math problem that could be solved by software. In practice, however, the exercise relies on a complex set of biological, chemical, and engineering assumptions; on maintenance of healthy cell cultures; and on management of equipment and analytics while adjusting to each increase in scale (1). Process development and quality control groups need to monitor how scale-up might affect critical quality…

Host Cell Protein Analysis: Immunoassays and Orthogonal Characterization By Antibody Affinity Extraction and Mass Spectrometry Methods
Reduction of Host Cell Proteins (HCPs) to the lowest levels practical requires sensitive and robust analytical methods. In this Special Report, Cygnus Technologies discusses industry best practices for HCP analysis and integration of orthogonal methods for in-depth HCP characterization using Antibody Affinity Extraction (AAE) and Mass Spectrometry (MS). Download the report to learn about: Antibody Affinity Extraction for HCP antibody coverage analysis to ensure HCP ELISA is broadly reactive and fit for purpose of process monitoring and product lot release…
