Chromatography

The separation of monomers from product-related impurities is quite challenging in process separations. It requires a thorough screening and an efficient resin to get efficiency in the purification process. Review the performance data of Bio-Rad’s mixed mode CHT™ Ceramic Hydroxapatite in achieving process separation efficiency and how it compares with various Capto media.

The best chromatography media should yield high protein purity and product recovery as well as be versatile enough to purify difficult samples. Bio-Rad’s CHT™ Ceramic Hydroxyapatite achieves this by virtue of being able to interact with the proteins through multiple modes, making the process extremely efficient. The whiteboard animation describes the mode of action of CHT.

What can chromatography peaks tell us? From the quality of column packing to the purity of separated proteins, a lot can be gleaned from the peaks. Here are some definitions that can help decipher what chromatography peaks can tell us.

Some of the frustrations in protein purification stem from unmet chromatography needs, such as automation, productivity, throughput, and reproducibility among others. Bio-Rad’s new Multi-D chromatography method addresses these and provides solutions to faster, efficient and more reliable protein purification.

Traditional sequential chromatography typically requires intensive hands-on user manipulation, which could hinder the reproducibility of protein purification runs. Multi-D chromatography aims to improve this process while maintaining the efficacy of the traditional workflow.

The NGC Chromatography System introduces a new level of modularity and usability for protein purification. The modular design of the NGC System provides multiple configurations, each addressing different requirements. Use our configurator tool to build your own system to meet your specific workflow and throughput needs.

What does automated protein purification mean today? What might it look like tomorrow? Bioradiations talks to a variety of users about what they’re doing now to implement automation in their purification processes, and what possibilities they envision that will improve chromatography in the near future.

While using affinity tagging is the preferred method to achieve highly pure protein through recombinant expression, this approach isn’t feasible for all proteins. This tech report describes workflow optimizations using the NGC Chromatography System that allow users to achieve high purities with untagged proteins.

Structural biologist Petr Novák employs the latest techniques to model natural killer cell receptor molecules, research that may one day result in powerful therapies to treat cancer and infections. Go inside the fascinating world of structural characterization and find out how Novák has integrated the NGC™ chromatography system into his effort to visualize these molecules in vivid detail.

In biochromatography, every purification or separation procedure that fails because of instrument malfunction wastes precious lab resources. That’s why Bio-Rad, in designing the NGC chromatography system, found new ways to engineer reliability into the chromatography experience. Here’s how they did it.
