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.

mAb Purification – an overview of the essentials

Posted by The Bio-Works Team on Apr 24, 2019 11:26:15 AM

Five of the top ten best selling drugs in 2017 were mAbs and the global mAbs market is expected to reach USD 219 billion by the end of 2023. The mAbs entering the clinic today are highly engineered and are presenting new challenges in purification. When patients are treated repeatedly with high doses and over long periods, the accumulative effects of impurities can be substantial, so the purity requirements of mAb drugs are very stringent. 

We've summarized some of the essentials of mAb purification to give you a quick and broad overview of this fast-growing and exciting field.

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.

Three market changes that will impact the production of mAbs

Posted by The Bio-Works Team on Jan 26, 2019 11:51:21 AM

In 2015, the monoclonal antibodies (mAbs) market was estimated to be USD 85,4 billion and predicted to reach approximately USD 130 billion in 2023[1]. However, new research points at a much higher number. According to Zion Market Research, the global mAbs market will reach USD 219 billion by the end of 2023[2]. The market growth was much higher than expected only a few years ago, and even this number might be surpassed as we approach 2023.

How pure is pure? Controlling your mAb purification process

Posted by The Bio-Works Team on Dec 12, 2018 8:53:58 AM

Monoclonal antibodies, mAbs, form a well-established, technologically advanced segment of the pharmaceutical industry offering hope for large groups of patients who have difficult-to-treat cancers, rheumatoid arthritis or other serious diseases. More than 50 percent of the biopharmaceuticals on the market today are mAbs and more mAb therapies are in the pipeline [1]. The quality requirements of mAbs are very stringent, leading to high costs of production as well as high treatment costs. In this article we will take a look at mAb purity and give an overview of two strategies that can be used to develop a suitably pure protein – In-process control and Quality by Design.
