Using Organoids for Disease Modeling

The culture of organoids has permitted researchers access to a highly physiologically relevant system for studying human disease. Human organoids reflect key structural and functional properties of organs such as kidney, lung, gut, brain and retina making them incredibly valuable, particularly in situations where there is an unmet need for an in vitro human model. While their value is undeniable, culturing organoids can be quite challenging. Many tools and techniques have been developed for organoid culture, however depending on the cell type, research area and experimental goals, it can be difficult to identify the right method. For this Ask the Expert Session, we have assembled a team of experts to answer your questions on disease modeling using organoids…

Improving expression and purification of mAb using FectoCHO® Expression System and MabXpure

Transient gene expression (TGE) is commonly used for medium scale production of recombinant proteins and antibodies in suspension CHO cell lines. This approach allows production of sufficient protein amounts for “proof of concept” studies or tools validation, prior to moving on to time-consuming, but cost-effective production of stable cell lines at large scale. Speed and flexibility of TGE has allowed this technique to be widely adopted in early phase discovery. There are two main bottlenecks in protein production that need to be addressed to make TGE profitable: increasing protein production yield and improving protein recovery yield…

Live Cell Analysis for Neuroscience Research

Novel affinity resins enabling the purification of next generation antibody fragments: KANEKA KanCap™ G and KanCap™ L

Ever since the licensing of first monoclonal antibody (mAb) drug, biologics have seen unprecedented growth as drugs to treat a variety of malignancies1. The modular structure of mAbs have allowed protein engineers to create smaller, nimbler, and multispecific next-generation antibody therapeutics. Some of these modalities can be easily produced using microbial expression systems, offering higher yields and excellent process economy2

Supplier Qualification and Material Selection – A Case Study of Biopharmaceutical Resin Manufacture

To ensure a safe and continuous supply of life-saving biopharmaceuticals, raw materials for biomanufacturing must be selected carefully and suppliers evaluated with much scrutiny. Several instances of drug shortages as the result of either a raw material shortage or contamination reinforce the need for thorough evaluation. Ensuring a reliable supply and the quality of the materials selected is of paramount importance…

Bioburden Control Strategies for Continuous Downstream Processing

Implementing continuous bioprocessing for biomanufacturing has been increasing in interest. As a result, questions have arisen about the implementation of this strategy for downstream processes. Of particular interest is maintaining a high degree of bioburden control in continuous downstream process. While bioburden control strategies for continuous processing focus on prevention, not unlike batch processing, many want to know if there are specific strategies that should be implemented with continuous bioprocessing that are different than those used in batch processing…

Cool Tool – Innovative sorbents enable a robust and streamlined protein purification process

Monoclonal antibodies have long been purified using a platform approach. This platform mainly consists of three chromatography steps. These include a Protein A based affinity chromatography step followed by polishing steps. The purpose of the affinity chromatography is to capture the mAb, while the polishing steps remove any remaining impurities, such as residual DNA, host cell proteins, viruses and aggregates. There are options in the selected polishing steps, but often they involve cation exchange or hydrophobic interaction. Increasingly membrane chromatography is being used as a polishing step to remove any remaining contaminants…

Optimizing mAb Purification with Highly Selective Mixed-mode Cation Exchange Sorbent

In today’s market, mAbs are produced for several therapeutic applications, yet they are not a homogeneous family of products. Each mAb is unique, based on its isoelectric point, hydrophobicity and ability to aggregate; the contaminant HCP content is also process-dependent. As drug manufacturers seek to produce mAbs for various application, they are also looking to streamline processes for efficiency and quality…
