Growth of Saccharomyces cerevisiae and Preparation of DNA.
Academic Article
Overview
abstract
This protocol describes methods for isolation of total DNA from a strain of Sacchromyces cerevisiae carrying a recombinant yeast artificial chromosome (YAC). This method is appropriate for preparing DNA that will be subjected to regular agarose gel electrophoresis, Southern blotting, subcloning, genomic library construction, polymerase chain reaction (PCR), or other methods that do not require intact high-molecular-weight DNA. Because the linear YAC DNAs are sensitive to shearing forces, pipettes with wide-bore tips should be used to transfer DNAs. Drop dialysis should be used to exchange buffers. The expected yield from a 10-mL culture is 2-4 µg of yeast DNA.
