Joaquin Gomis Fons (Lund Univeristy) has recenetly published another article about the Optimization of a periodic counter-current chromatography (PCC) integrated in a downstream process for the purification of monoclonal antibodies  in Jornal of Chromatography A

Highlights:

- Optimal values of capture productivity and resin utilization were obtained from a model-based optimization.

- This is the first (to our knowledge) study of the integration alternatives of multi-column continuous chromatography in a downstream process. 

- Integration approaches with higher cycle time leads to lower productivity.

- The integrated downstream process was validated experimentally at lab scale with two ÄKTA pure systems.

Update: 2020/04/08

Joaquin Gomis Fons (Lund Univeristy) and Hubert Schwarz (KTH) have have published their article about the Model‐based design and control of a small‐scale integrated continuous end‐to‐end mAb platform  in Biotechnology progress.

Highlights:

- A 200 mL ATF perfusion bioreactor and a single chromatography system were integrated in a compact design.

- Real-time model-based control strategies in the downstream process were implemented to achieve an automated and optimal operation.

- A maximum productivity of 0.8 mg/mL day of purified product was obtained, with a recovery time of less than 4 hours.

Mingliang Wang (Post-Doc at AdBIOPRO) has published his article about the Identification of nonlinear kinetics of macroscopic bio-reactions using multilinear Gussian processes  in Computers & Chemical Engineering. 

Update: 2020/01/13

Hubert Schwarz (PhD student at AdBIOPRO) has now published his article about very high cell density perfusion process in small-scale bioreactor perfusion system in J. of Biotechnology. The article is available at the link below (free of access until Feb 18, 2020).

www.sciencedirect.com/science/article/pii/S0168165619309538

Highlights:

- Cell densities of HEK293 cells and CHO cells maintained at 80 and 100 x 10^6 cells/mL 

- Novel small-scale perfusion bioreactor system for animal/human cells with working volumes < 250 mL

- Very low cell specific perfusion rate down to 10 pL/cell/day

- HEK293 cell expressing Erythropoietin cultured in high cell density perfusion process more than 75 days
