Tools for improving yields and purity from recombinant bacterial proteins

Presented by

Garry K. Seward, PhD., Product Manager, Molecular Workflow Tools

About this talk

Various methods for the extraction and purification of recombinant proteins from bacteria are in use and have been well described. Common methods for cell lysis involve mechanical disaggregation of cells, such as sonication, but this can be time-consuming when working with multiple samples and more importantly can result in localized heating leading to loss of protein activity. In this webinar, we provide data showing that gentle detergent based lysis leads to greater protein activity and higher yields when compared to mechanical methods such as sonication. We also investigate the use of dual purification strategies and explore optimizing conditions to improve the purity of protein purification techniques.
