Summary

Yeast is a useful model organism to study the genetic and biochemical mechanisms of aging. Genomic studies of aging in yeast have been limited, however, by traditional methodologies that require a large investment of labor and resources. In this chapter, we describe a newly-developed method for quantitatively measuring the chronological life span of each strain contained in the yeast ORF deletion collection. Our approach involves determining population survival by monitoring outgrowth kinetics using a Bioscreen C MBR shaker/incubator/plate reader. This method has accuracy comparable to traditional assays, while allowing for higher throughput and decreased variability in measurement.

Key words
