Automation and disposable technology have offered considerable efficiency improvements to speed cell line development; however, a major challenge with process development for biologics is how labor intensive it can become. Many different interactions and parameters can impact product quality and product titer, which typically requires iterative rounds of statistical experimentation using up to 20 reactors or more per study. For cell culture mAb processes, this development work can take three to four months to complete, which adds considerable cost for a company in multiple ways. Because of this challenge, Dr. David Pollard, executive director of BioProcess Technology & Expression, BioProcess Development at Merck, and his dedicated technology group wanted to see how the benefits of automation and disposable technologies could be translated into tools to drive high throughput upstream process developmen
At Ferring Pharmaceuticals, Peptides And Proteins Make Significant Advances
Dr. Keith James joined Ferring Pharmaceuticals as VP of Therapeutic Innovation in early 2012. In December 2012 he was promoted to president of the Ferring Research Institute and SVP of R&D for Ferring Pharmaceuticals. Prior to joining Ferring, Dr. James spent 29 years working for Pfizer, with significant time spent in discovery research. At the 2013 Oligonucleotide & Peptide Based Therapeutics Congress he will speak on recent progress and future prospects in the peptide and protein therapeutic space. I recently spoke with Dr. James to get an overview of the potential in this market.
Fundamentals Of Viral Clearance Studies Part 4: Considerations For Evaluating Viral Clearance By Chromatography Steps
Chromatography steps are typically the backbone of the purification process for a biopharmaceutical product, and are usually included in the evaluation of the viral reduction capacity of a manufacturing process. In viral clearance studies of chromatography steps, the capacity of the chromatography resin to provide physical separation of the spiked virus from the product fraction is determined. Viral reduction by chromatography steps is considered less robust than by other less complex steps, such as inactivation steps.

WHITE PAPERS & CASE STUDIES
Golden Rules For Working With Cell Cultures
Susi and Adi know from their own (sometimes bitter) experience the sort of things that cause problems for them and their colleagues in cell culture bottles in the lab.
Scale-Up Of Microbial Fermentation Using Recombinant E. Coli
Fermentation production facilities can utilize the Thermo Scientific™ HyPerforma™ Single-Use Fermentor (S.U.F.) instead of traditional stainless steel cleaning-in-place/ sterilization-in-place (CIP/SIP) fermentor vessels without modifying their existing procedures.
Adaption Of The BioLector Technology To Anaerobic Requirements
Biorefineries have reignited interest in anaerobic fermentations with biobutanol production being the principle driver. Already during the First World War Biobutanol and acetone were produced in Clostridium acetobutylicum.
Batch Culture Of CHO Cells In The Multifors Cell
The Multifors Cell can be used to easily optimise development processes by parallel cultivation of animal cell cultures. Cultivation of the CHO (Chinese hamster ovary) cell line in the Multifors Cell bioreactor (INFORS HT, CH-Bottmingen) is described in the following as an example of batch cultivation of parallel samples.
High Density Hybridoma Cell Culture In A Packed-Bed Bioreactor
Packed-bed bioreactor cell culture is generally accepted as one of the best methods to simulate the conditions of animal cell growth in vivo since cells are maintained in a low-shear environment with constant refreshment of nutrients and removal of waste. By Ray Rose, Stacey Willard, and Ma Sha
Anaerobic Yeast Fermentation Using Redox Control
Metabolic activity of microorganisms depends on many factors, including oxidation and reduction reactions, or the “redox potential” of the culture environment.

Cell culture is a complex, highly structured process for growing cells, under strictly controlled conditions, outside of their normal environment. Cell cultures stilluse cultures of cells on flat plastic dishes.
This is referred to as two-dimensional (2D) cell culture. Aside from using Petri dishes for growing cells, scientists have for a long time, grown cells within biologically-derived matrices such as collagen or fibrin.
Today, more and more 3d cell cultures are being used because they more closely resemble the in vitro cell growth environment. Most 3d cell cultures in use today are designed for stem cell research, tissue engineering and drug discovery. As the field continues to grow and expand, 3d cell culture availability will likely expand to include other cell culture related fields.
For non-adhesive cells suspension cell cultures are used. In these cultures a cell is placed in the liquid suspension, stirred with a magnetic stirrer to agitate the cell and make it float freely in the suspension. The cell grows, divides and spreads throughout the suspension.
Cell culture refers to the culturing of cells derived from multi-cellular eukaryotes (cells with a nucleus), primarily animal cells. However cell cultures also exist for plants, fungi and microbes that include viruses, bacteria and microorganisms. Cell culture shares closely related methodology with tissue culture and organ culture.
You can separate cells from tissues for use in cultures several ways. Cells can be purified from blood but only white cells will grow in a culture. Mononuclear cells can be released from soft tissue using enzymes that break the cells away from their substrate or matrix. Pieces of tissue can also be placed in a growth media and the cells that grow from it can be used for cell cultures.
