Setting up a perfusion process is complex, and getting the best out of it requires an awareness of the do’s and don'ts of the approach. Design of experiment (DoE) and quality by design (QbD) approaches help the development of a production process that is both cost-effective and high quality.
As biotechnology takes a greater role across different industries, a standardized color code system has been created to describe the different roles and applications.
Upstream processes must be robust to ensure high batch success rates with a low risk of contaminations and minimal variations in cell growth performance.
With the continuing move toward the use of animal component- free materials in biomanufacturing processes, Pall Life Sciences has added a new, animal component-free microcarrier to its portfolio.
mAbs are produced for a number of therapeutic applications. mAbs are not a homogeneous family of products. Each mAb is unique, based on its isoelectric point, hydrophobicity, and ability to aggregate.
Mycoplasma maybe the smallest class of free living microorganism, but the consequences of a contamination in a cell batch during bioprocessing can be huge.
This case study explains how Parker Domnick Hunter (a division of Parker Hannifin) helped a pharmaceutical company optimize cell density in cell culture tanks that needed to be converted into fermenters to grow E. coli bacteria.
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.
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.
Mixed-mode chromatography resin is a top tier selection for the manipulation, purification and handling of molecules; providing an unmatched level of separation properties and resolution. The combination of cation exchange resin and metal affinity resin properties, allows multimodal chromatography to provide an access route for biomolecules to separate and the use of alternative chromatographic methods make these biomolecules seem homogenous.
The S.U.F. is engineered for optimal oxygen mass transfer, mixing, and temperature control, and performs comparably to traditional stainless steel systems. Using traditional, fundamental engineering principles, scale-up and process development work is streamlined – offering you cost savings and efficiency.
In March 2014, GE Healthcare Life Sciences announced the completion of the acquisition of the HyClone cell culture media business from Thermo Fisher Scientific. The addition of the HyClone portfolio significantly broadens our existing capabilities in life sciences research and bioprocessing. The result is a comprehensive portfolio of products and services across the whole biomanufacturing workflow, from upstream to downstream, from discovery to commercialization.
BalanCD® MDCK has been designed for producing viruses in Madin-Darby Canine Kidney cells (MDCK) cultures. This medium is chemically-defined and animal-component-free.
The Biolector® Pro is the first microbioreactor system combining the proven, scalable BioLector® technology with an innovative microfluidic chip.
With the launch of the Minitron incubator shaker, INFORS HT is following up on the worldwide success of the Multitron incubator shaker. The Minitron has the same outstanding characteristics as its big brother, the Multitron, but on a smaller scale.
WHEATON understands that when it comes to BioBanking, sample integrity means everything.
WHEATON BioBanking Solutions include color coded storage and freezer boxes to make your sample storage and tracking solutions customized and easily identifiable.
America's biopharmaceutical companies are using biological processes to develop 907 medicines and vaccines targeting more than 100 diseases, according to a new report released today by the Pharmaceutical Research and Manufacturers of America (PhRMA).
Baxter International Inc. has begun dosing patients with malignant solid tumors in a Phase I clinical trial of a monoclonal antibody, representing the company’s efforts to extend its oncology portfolio with advanced biological research and development.
Cell Culture
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.
