Protocol for spore germination. This procedure is typically used for the isolation and preparation of spores from a diploid strain heterozygous for a marked disruption (e.g., yfg1::his3+) Inoculation of the spore population into minimal medium lacking the nutritional supplement corresponding to the disruption marker (e.g., minimal medium lacking histidine) allows only the disruption spores to germinate. - [Read Spore Germination Protocol]
The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
