Enhanced Capture Process - a presentation

Posted by The Bio-Works Team on Jan 9, 2020 9:11:51 AM

Just before the Christmas break, Lars, Haneskog, Bio-Works R&D Director, presented a new and proven strategy for downstream processing at the New Horizons in Biologics and Bioprocessing conference. It was met with great interest and several enquiries and, for those that missed it, we asked Dr. Haneskog to give us a brief summary of what was discussed.

QuickTip #3: optimizing mAb purification

Posted by The Bio-Works Team on Oct 14, 2019 1:38:24 PM

Designing an optimized purification process means maximizing yield and purity, and at the same time controlling costs. So, you remove a lot of bulk impurities during the first steps, and focus on high yield steps at the end, when every gram is precious. If you’re purifying mAbs, it would also be good to remove impurities before affinity chromatography to protect the protein A column and reduce the need for cleaning in place (CIP).

Improved peptide purification promises to boost process efficiency in the race to affordable insulin in China

Posted by The Bio-Works Team on May 29, 2019 9:57:45 AM

The global diabetes pandemic has created a massive demand for insulin, especially in China, which is expected to soon have half the world’s diabetes patients. Meeting this demand means developing extremely efficient production methods that can supply affordable insulin with high purity. A promising approach is to add an orthogonal step upstream the main reverse-phase chromatography (RPC) peptide purification to increase purity and also guard the expensive high-performance RPC columns from bioburden and stringent cleaning-in-place procedures.

How to improve process efficiency and economy in peptide production

Posted by The Bio-Works Team on May 16, 2019 11:29:13 AM

The purity requirements for therapeutic peptides are very stringent, but synthesis generates a crude peptide mixture containing failed sequences and chemical variants, while recombinant peptides have a considerable bioburden from the host cell. These crude feeds can foul the reverse phase chromatography (RPC) columns commonly used in peptide purification. Introducing an orthogonal purification step upstream significantly reduces the burden on the expensive high performance RPC column, increases the peptide yield and purity, and also prolongs column lifetime.

Optimizing mAb purification using the next generation of protein A resin

Posted by The Bio-Works Team on Apr 10, 2019 1:52:57 PM

The market for monoclonal antibodies (mAbs) is constantly growing as mAb therapies are generally considered to be both safe and effective treatments for difficult diseases like cancer and rheumatoid arthritis. The growing global demand, as well as increasing competition, puts pressure on manufacturers of mAb products to improve their operations. There is a need for more efficient resins, as well as for innovative strategies to continuously improve purification processes. Bio-Works resins provide many benefits that help you improve your mAb purification process while at the same time achieving cost efficiency in your production.

Optimizing mAb purification using a guard column

Posted by The Bio-Works Team on Feb 11, 2019 4:11:57 PM

What are the benefits of introducing multimodal ion exchange chromatography as a guard column and could they include a significant increase in mAb purity? This article presents a study in which two protein A affinity chromatography resins were compared to see whether the introduction of a guard column could improve mAb purity and to discover which of the protein A resins produced the best results.
