| description | Progress in aging research is constrained by the time requirement of measuring lifespans. Even the most rapid model for eukaryotic aging, the replicative lifespan of Saccharomyces cerevisiae, is technically limited to only several lifespan measurements each day. Here we report a 384-well plate-based technique to measure replicative lifespan, termed High-Life. Using the High-Life technique, a single researcher can compare lifespan for more than 1,000 conditions per day. We validated the technique with long-lived mutant strains and the lifespan-extending compound ibuprofen. We also applied this technique to screen a small compound library for lifespan extension. Two hits, terreic acid and mycophenolic acid, were validated on our single-cell replicator device and found to extend mean replicative lifespan by 15% and 20%, respectively. Together, we report a technique for high-throughput lifespan measurement, and we identify two lifespan-extending compounds. Our technique could be used to efficiently drive early-stage discovery of pro-longevity therapeutics. |
