Inflammation Linked to Colon Cancer Metastasis
A new Arizona State University research study led by Biodesign Institute executive director Raymond DuBois has identified for the first time the details of how inflammation triggers colon cancer cells to spread to other organs, or metastasize.
New Strategy for Combating Adenoviruses
Using an animal model they developed, Saint Louis University and Utah State university researchers have identified a strategy that could keep a common group of viruses called adenoviruses from replicating and causing sickness in humans.
Major Advance Toward More Effective, Long-Lasting Flu Vaccine
Collaboration shows vaccine candidate can produce powerful ‘broadly neutralizing antibodies’ in animal models.
Immune System: Help for Killer Cells
A study from the University of Bonn may show the way to more effective vaccines.
Protein Found to Control Inflammatory Response
A new Northwestern Medicine study shows that a protein called POP1 prevents severe inflammation and, potentially, diseases caused by excessive inflammatory responses.
A Leap Forward in Vaccinating Against HIV
A team of scientists has developed an experimental vaccine candidate that successfully stimulates the immune system activity in animal models necessary to stop HIV infection.
MRI Scanners Can Steer Therapeutics to Specific Target Sites
Scientists from the University of Sheffield have discovered MRI scanners, normally used to produce images, can steer cell-based, tumour busting therapies to specific target sites in the body.
Agricultural Intervention Improves HIV Outcomes

Direct Visualisation, Sizing and Counting of Aggregation in Proteins

NanoSight Ltd

A wide variety of aggregates are encountered in biopharmaceutical samples ranging in size and characteristics (e.g., soluble or insoluble, covalent or noncovalent, reversible or irreversible). Protein aggregates span a broad size range, from small oligomers (nanometers) to insoluble micron-sized aggregates that can contain millions of monomer units. 

Protein aggregation can occur at all steps in the manufacturing process (cell culture, purification and formulation), storage, distribution and handling of products. It results from various kinds of stress such as agitation and exposure to extremes of pH, temperature, ionic strength, or various interfaces (e.g., air–liquid interface). High protein concentrations (as in the case of some monoclonal antibody formulations) can further increase the likelihood of aggregation. 

Therefore, aggregation needs to be carefully characterised and controlled during development, manufacture, and subsequent storage of a drug substance and formulated product. Similarly, by monitoring the state of aggregation, modification or optimisation of the production process can be achieved.
