Come relax and network with your contemporaries and senior biophysicists over a beer or glass of wine. This event is a great chance to compare notes with colleagues and discuss one-on-one your unique solutions to issues that arise in the time between getting your job and getting your next promotion, including management of lab staff, getting your work published, and renewing your funding. Refreshments will be provided, with cash bar. Exhibitor Presentation: Fluidic Analytics 4:30 pm - 6:00 pm, Room 10 Introducing Microfluidic Diffusional Sizing (MDS) Technology; Quantify and Characterize Any Protein Interaction – Even in Complex Backgrounds, Even with Challenging Targets Studying protein interactions is of fundamental importance in a wide variety of research fields, including neurobiology, oncology, immunology, structural biology, and molecular biology. The more scientists understand about protein interactions, the more we will know about the inner workings of a cell, and crucially, the better we will understand what happens when normal cellular function is subverted in human disease. But, with a multitude of different technologies on the market, how do researchers know which technique is right for them? Microfluidic Diffusion Sizing technology (MDS) brings a new tool to the analytical characterization toolbox: a different approach that enables the analysis of protein interactions close to in vivo conditions. Measuring What Matters With MDS, scientists can determine affinity of interaction (KD), concen -
