The replicative aging of the budding yeast, Saccharomyces cerevisiae, has been a useful model for dissecting the molecular mechanisms of the aging process. Traditionally, the replicative lifespan (RLS) is measured by manually dissecting mother cells from daughter cells, which is a very tedious process. Since 2012, several microfluidic systems have been developed to automate the dissection process, significantly accelerating RLS determination. Here, we describe a detailed protocol of RLS measurement using a ommercially available microfluidic system based on the HYAA chip design, which enables data collection of up to 8000 cells in a single experiment.
