In this second edition of a widely used classic laboratory manual, leading experts utilize the tremendous progress and technological advances that have occurred to create a completely new collection of not only the major basic techniques, but also advanced protocols for yeast research and for using yeast as a host to study genes from other organisms. The authors provide detailed methods for the isolation of subcellular components-including organelles and macromolecules, for the basic cellular and molecular analysis specific for yeast cells, and for the creation of conditional mutant phenotypes that lend themselves to powerful genome manipulation. Additional protocols offer advanced approaches to study genetic interactions, DNA and chromatin metabolism, gene expression, as well as the foreign genes and gene products in yeast cells.
