Category: Yeast Protocols: Yeast Genetics Protocols: YACs Protocols

Protocol describes methods for isolation of DNA from a strain of S. cerevisiae carrying a recombinant YAC. Because the linear YAC DNAs are sensitive to shearing forces, pipettes with wide-bore tips should be used to transfer DNAs. The method is suitable for preparing DNA that will be used for agarose gel electrophoresis, Southern blotting, subcloning, genomic library construction, PCR, or other methods that do not require intact high-molecular-weight DNA. - [Read Growth of S. cerevisiae and Preparation of DNA Protocol]

Category: Yeast Cell Culture Protocols: Yeast Media, Solutions and Stocks Protocols

The yeast, Saccharyomyces cerevisiae, has become an important organism in molecular, biochemical, and genetic analysis. The organism has specific requirements for growth under a variety of conditions. The media, both liquid and solid, simple, define, and complex are describe in this unit. Also included are methods for handling, storing, and shipping stock of yeast. - [Read Media and Culture of Yeast Protocol]

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols: Peroxisome Isolation Protocols

To isolate peroxisomes from Saccharomyces cerevisiae of a quality sufficient for in vitro import studies, we optimized the conditions for cell growth and for cell fractionation. Stability of the isolated peroxisomes was monitored by catalase latency and sedimentability of marker enzymes. - [Read Peroxisomes in Saccharomyces cerevisiae]

Category: Yeast Protocols: Yeast Nucleic Acid Protocols: Yeast DNA Isolation Protocols

This method is used to isolate genomic yeast DNA or shuttle plasmids that replicate in both S. cerevisiae and E. coli. The DNA can be used as a template for PCR and for transformation. - [Read Rapid Isolation of Yeast DNA Protocol]

Category: Pharmacology and Toxicology Protocols: Cytotoxicity Protocols: Microorganism Cytotoxicity Assays Protocols

The proliferation rate of the yeast, Saccharomyces cerevisiae, may be regarded as an overall indicator of the physiological status of the cell.  Therefore, the effect of various toxic substances on different cell functions will be reflected by changes in the rate of proliferation.  It is possible to determine the toxicity of a test substance simply by measuring cell density. - [Read Yeast Growth Rate Cytotoxicity Test]

Category: Yeast Protocols

Plasma membranes are isolated from the yeast Saccharomyces cerevisiae. The cell wall is initially digested by helicase, followed by hypoosmotic lysis and homogenization. Membranes are prepared by subsequent differential centrifugation. The activity of the H+-ATPase is then determined by measuring the amount of inorganic phosphate released from ATP. - [Read Yeast Plasma Membrane H+ -ATPASE Toxcity Test Protocol]
