CapSenze Flow System

  • Overview

    The Capsenze Flow System is designed to sample a bioreactor and automatically digest and separate individual antibody subdomains for direct analysis by mass spectrometry and/or other technologies. The system is built on CapsSenze´s unique liquid handling system and adapted for use with Genovis enzymes.

    The system automatically samples from the bioreactor and process the mAb to provide subunits, utilizing affinity matrices and unique enzymes integrated into a disposable column cartridge. As a result, it is possible to characterize the whole mAb via fragments analyse done-by-one, thus enabling a very high level of quality assurance directly during production.
