We modified both Bio Rad NGC and ÄKTA Pure systems to run a three-column process (ProA to buffer exchange to SEC) enabling automated tandem affinity to SEC purification while minimizing the risk of SEC column fouling and subsequent cross-contamination. However, the harsh elution conditions from ProA based chromatography can destabilize some proteins resulting in particulates, which in turn can cause column fouling and potential cross-contamination of subsequent purifications. With the need for higher throughput protein production increasing for discovery research, there is substantial interest in the automation of complex protein purification processes, which often start with a ProA step followed by SEC. "This means less time spent training and more time spent purifying," Mr Fraser concluded.Affinity purification, such as Protein A (ProA) followed by size exclusion chromatography (SEC) remains a popular method to obtain research scale proteins. "Protein purification can be a challenging for many researchers, but by using the NGC family of medium pressure modular chromatography systems, this step can be completed more quickly and efficiently."Ĭhris Fraser, assistant professor at UC Davis, California, said he has tested the new suite and found the ease of use was perfect for a mix of grad and undergrad students. "The NGC Chromatography platform is an intuitive and flexible system that's simple to customise and effortless to use," he explained. Many components of the fluidics scheme can be controlled on-the-go to ensure optimal separation conditions, while the systems themselves can be controlled using the attached touchscreen interface, which offers the same level of control flexibility without the need for a computer adjacent to the system, explained Kamni Vijay, Bio-Rad division marketing manager for the Protein Function Division, Life Science Group. The instrument controls have been designed around a novel fluidics scheme interface that is fully customisable, according to the company, which noted that software can provide real-time fluidics path and module status to guarantee accuracy. The various functions of the NGC system are controlled by Bio-Rad's ChromLab software, which includes instrument control, method development, real-time monitoring, chromatogram comparison and peak analysis. Wash the column with 35 column volumes of buffer. Richard Lee, Bio-Rad marketing manager for Laboratory Chromatography Products, Life Science Group, commented: "Customers have been extensively involved in the development of the NGC systems and we are pleased to see how well the instruments have performed in their labs." Disposable chromatography columns are commercially available from Bio-Rad or other manufacturers. These medium pressure chromatography systems are the first of their kind, according to the company, which is a multinational manufacturer and distributor of life science research and clinical diagnostic products. The NGC medium pressure modular chromatography systems will be launched in the coming weeks alongside a new suite of plug-and-play modules that Bio-Rad says will enable researchers to expand the system's capabilities. Bio-Rad Laboratories has unveiled its new suite of protein purification systems, which enables users to modify their capability based on the user's changing requirements.
