Promega Webinars

NA_webinarsConcept-image
Welcome to the Promega Webinar Series, an ongoing communication designed to keep you informed. Learn about basic concepts, tips and techniques to help your research, or understand how products were designed and how to implement in your lab. Most presentations are given by Promega scientists and you will have an opportunity to interact with our Technical Service Scientist directly during live events via chat. The webinars are free though we do ask that you register for the events. Registration allows us to send you the URL for the webinar.

Applications of a Bioluminescent Peptide Tag: Simple, Quantitative Protein Detection Down to Endogenous Levels

Cell-Based Assays

Tuesday, September 26, 2017

Christopher Eggers, PhD

Regulated protein abundance and surface expression are fundamental to normal cellular physiology and dysregulation underlies many disease states. Monitoring changes in protein abundance usually involves labor-intensive, antibody-based methods that yield only semi-quantitative results. This webinar will introduce a bioluminescent tagging system that can quantify proteins in minutes using simple, antibody-free methods. This system offers wide dynamic range and sensitivity compatible with detecting even endogenously expressed proteins when combined with CRISPR gene editing.

Improved Chemistry for NGS Library Cleanup and Size Selection

Genomics

Tuesday, October 10, 2017

Charles Cowles, PhD

Current size-selective DNA purification methods need improvement with respect to sample loss, poor reproducibility, high viscosity and recovery of undesired high MW fragments. With new size selection chemistry, you can improve yield, selectivity, usability, and functionality in NGS library cleanup and size selection, as well as PCR cleanup and other applications.

A Practical Guide to CRISPR-Mediated Gene Tagging with a Bioluminescent Peptide

Cell-Based Assays

Tuesday, October 24, 2017

Marie Schwinn, PhD

CRISPR/Cas9 gene editing has emerged as a powerful tool for making precise genomic modifications. Although often used to create gene knockouts, the technology also enables targeted knock-in of a specific sequence. An exciting application is the endogenous tagging of proteins expressed under native regulatory conditions. In this webinar, we will detail a simple and efficient cloning-free method for CRISPR-mediated endogenous gene tagging, focusing on knock-in of the sensitive, bioluminescent HiBiT tag.

Bioactivity Assays: Putting the Puzzle Together

Drug Discovery

Tuesday, September 19, 2017

Ulrike Herbrand, PhD

In past years, the requirement for bioactivity testing changed from later phase lot release and stability testing to additional applications like biocomparability testing for follow-on biologics, accelerated stress condition testing and confirmation of successful production scale up. Therefore a suitable bioassay is needed at a very early time point. This webinar will look at a wide variety of therapeutic proteins and illustrate some best practices in method development that results in reliable, reproducible and precise assays, and discuss which assays may be best for your product and development program.

How to Integrate Cellular Metabolism Assays Into Your Research: Considerations and Challenges

Cell-Based Assays

Tuesday, September 12, 2017

Donna Leippe, PhD

Metabolite detection technologies can pose challenges such as laborious sample preparation and the inability to assay numerous samples rapidly. Additionally, lack of sensitivity and dynamic range prevents detection of metabolites directly in cells in multi-well plates. In this webinar, we describe new bioluminescent metabolite assays and sample processing strategies that enable rapid measurements of key energy metabolites in plate formats and show how the assays can be used to study cancer cell metabolism and activation of T cells.

How to Avoid Artificial Non-Enzymatic PTMs During the Peptide Sample Preparation Process

Proteomics

Tuesday, June 13, 2017

Sergei Saveliev, PhD

Non-enzymatic post-translational modifications (PTMs) spontaneously occur in biotherapeutic proteins during manufacturing and storage. These modifications negatively affect efficacy and stability of biotherapeutic proteins. Major non-enzymatic PTMs are deamidation, disulfide bond scrambling and oxidation. These non-enzymatic PTMs are also introduced during protein preparation for peptide mapping and compromise the analysis. In the webinar recording Dr. Saveliev discusses sources of these artificial protein modifications as well as procedural optimizations to suppress these PTMs.

Post-Translational Modification Enzymes: How to Interrogate Key Drug Targets

Cell-Based Assays

Tuesday, April 11, 2017

Hicham Zegzouti, PhD

Post-translational modifications (PTMs), the addition of functional groups to proteins, play a significant role in regulating cellular biology. Examples include phosphorylation, a common mechanism in regulating enzymatic activity, and the addition of carbohydrates to many eukaryotic proteins, which promotes proper folding, improves stability and serves in regulatory functions. A key objective of research and drug discovery surrounding PTMs is to study the regulation of these enzymes and find specific modulators of their activity. Although mass spectrometry, eastern and western blotting detection technologies have been used traditionally, none are amenable to high throughput or as sensitive as bioluminescent detection of nucleotide-based substrates for such enzymes.

Optimizing and Qualifying Reporter Gene Bioassays for Immune Checkpoint Receptors

Drug Discovery

Tuesday, March 28, 2017

Zhijie Jey Cheng, PhD

Reporter gene assays for functional screening and development of antibody drug candidates are gaining popularity due to the significant advantages they offer over traditional methods that rely on human primary immune cells. We will discuss development of a series of MoA-based reporter gene bioassays for antibodies targeting co-inhibitory receptors, co-stimulatory receptors and combination bioassays that target immune checkpoint receptors.
