Biogen IDEC - On-line Amino Acid Analysis from a Small Scale CHO Cell Bioreactor Acrobat PDF
This Application Note describes a fast, accurate and reproducible measurement of 21 amino acids in a Chinese Hamster Ovary (CHO) cell culture using an online HPLC instrument. The hyphenated system combines the automatic sampling and reactor sterility protection of the Groton ARS with a high performance amino acid separation system provided by the Agilent 1100 Series HPLC System. The set-up, which is described in this Application Note, was used for in-process analysis during the course of a 14-day bioreactor run, which has been previously demonstrated using pulsed amperomeric detection. This tool provides immediate sampling and testing of a bioreactor that does not compromise bioreactor or samples, reduces hands on work and improves in-process monitoring of a bioreactor.

DASGIP/YSI/Groton - Automated On-Line Real Time Reactor Feedback Control Acrobat PDF
Integration of the Groton Automated Reactor Sampler, the DASGIP Bioreactor and the YSI Biochemistry Analyzer - Bioprocess monitoring and control of key analytes such as glucose, lactate, amino acids, and ammonia levels is critical to obtain optimal and consistently high productivity of a cell culture system. Improved productivity is critical to the development of high efficiency, economical production processes for therapeutic proteins and monoclonal antibodies. Despite the apparent value of feedback control systems in the biopharmaceutical industry there are few successful demonstrations. Here we present a complete, closed loop feedback control system by integrating a Groton Biosystems Automated Reactor Sample System with an YSI biochemistry analyzer and a DASGIP bioreactor control system in order to achieve a powerful, automated online, real time feedback control system for mammalian cell culture. With real time sampling and feedback control we provide an effective and efficient tool for the optimization of mammalian cell culture bioprocess. This system can easily be adapted to other types of manufacturing systems for biologics, for example, microbial fermentation. In addition, this system would also promote the FDA Process Analytical Technology (PAT) initiative.

Genentech - Implementing an Automated Reactor Sampling System for Monitoring Cell Culture Bioreactors Acrobat PDF
Process Development Engineering. Monitoring of cell culture bioreactors is critical to process control and optimization. Currently offline sampling is used in various cell culture operations. This process is time consuming and labor intensive. Automating the sampling process is highly desired but concerns about sterility, sample volume and cross contamination are common. This paper presents the evaluation of an automated sampling system by Groton Biosystems.
