If you have ever wondered about the differences between the various cell viability and cytotoxicity assays available, why you would choose one over another or how they can be used together, tune in to the webinar “A Real-Time Cytotoxicity Assay That Delivers More Relevant Data” (Tuesday, Sept 10). In this webinar, Promega Scientist Drew Niles explains how various metabolism and biomarker-based viability and cytotoxicity assays work, and describes how they can be used most effectively to give maximum information about mechanism and timing of cell death.
“Is a cell treatment toxic?” and “Why are the cells dying?” are questions that can be difficult to answer simply. The answer depends on dosage, treatment time, mechanism of action of the test compound, and the cell type used—and may sometimes be limited by features of the assay itself. For example, many viability and cytotoxicity assays measure biomarkers that are themselves subject to degradation over the course of longer experiments, complicating the interpretation of results. Drew provides an explanation of these issues and illustrates the critical role of timing in deciding on the assay to use and in interpreting results.
Drew will also cover how the CellTox™ Green assay—a new cytotoxicity assay that measures DNA release from dead/dying cells—can be used to continuously monitor changes in cell viability over time. The assay is non-toxic, allowing multiple viability timepoints from a single sample, giving a picture of cell health in great detail over the course of an experiment. Because the CellTox™ Green Assay reagent is non-toxic it also allows easy multiplexing of the cytotoxicity assay with other cell health assays.
Why multiplex? Drew will answer this question and provide example assay data showing exactly how real-time measurement of cytotoxicity, combined with measurement of cell viability markers and apoptosis assays can be used very effectively to gain valuable information about the mechanism of action of different test compounds in a single experiment.
The Webinar will last about 45 minutes and will include live chat to allow your questions to be addressed directly. Check it out if you are looking for answers on how to best use the various assay methods available to gain information about how, when and why cells die after exposure to test compounds, biologicals, transgenes or other potentially toxic events.
