Webinar: Journey of Protein from Extraction to Purification

30 October 2017


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 seminar, 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.

Webinar: Trusted Tools and Innovation in General and Specialty Cell Culture

15 November 2017


Cell culturing represents a fundamental research tool for life scientists by offering a unique ability to grow, manipulate, and analyze populations of cells.  From experiments utilizing the latest gene editing technologies to simple growth assays, high quality tools to ensure reproducible and reliable cell culturing is critical for the success of any life science projects. In this webinar, key considerations for choosing the right tools for various aspects of cell culturing will be presented. Starting from sterile filtration and cell enumeration through micro-porous membrane based functional assays and live cell imaging, audiences will be able to gain insights into parameters affecting cell culturing such as the choice of membranes and pore sizes and also learn about innovative microfluidics based tools for cell enumeration and culturing.

Webinar: Not All Spots are Created Equal: Maximizing ELISpot Data Quality through Workflow Optimization

12 December 2017


Precise regulation of lymphocyte function is critical to mounting a specific immune response; this complex process requires exquisite control of processes regulating expression of effector capabilities. Understanding such mechanisms is essential for the development of therapeutics that enhance endogenous immune function. While no one assay can measure all parameters, the ELISpot offers quantitative assessment of effector function(s) at the single cell level with superior sensitivity. MilliporeSigma and its collaborators have significantly improved upon ELISpot user-success rates through advances in plate/membrane technologies, including fluorescent applications, as well as optimized protocols to meet the common pitfalls of this assay. This webinar will focus on two key aspects of the assay that can greatly impact overall performance: choice of plate configuration and the role of apoptotic cells.
