Poster on
rapid fungal DNA typing from ASM 2006 (2.3 MB)
Applications
- Purification of DNA from yeast for many molecular biology applications,
including PCR amplification, restriction endonuclease digestion, Southern
blotting, and genomic library preparation.
- Identification and typing of fungi.
The MasterPure™ Yeast DNA Purification Kit enables efficient, high-yield
purification of high-molecular-weight DNA from yeast and other fungi. The
protocol involves nonenzymatic cell lysis at 65°C, followed by removal
of protein by precipitation, and nucleic acid precipitation and resuspension.
No lyticase, proteolytic enzymes, or bead-beating are used in the procedure.
Yeast genomic DNA yields using the MasterPure Kit are much higher than yields
obtained with other commercially available kits (Fig. 1).1 The
protocol can be easily adjusted for larger or smaller samples, including
single yeast colonies.1 The recovered nucleic acid can be used
directly in most applications, including PCR amplification.
Benefits
- Higher yields of yeast chromosomal DNA than with other kits.
- Recover DNA from a wide variety of yeast species, including Candida, Saccharomyces, Pichia,
and Schizosaccharomyces, and filamentous fungi such as Aspergillus2 and Penicillium.
- Purify DNA in less than 40 minutes.
- No enzymatic lysis, columns, or phenol or other organic extractions.
No bead-beating.
- The recovered DNA has a high molecular weight (Fig. 2), and is suitable
for many applications, including PCR amplification.

Figure 2. Size distribution of DNA produced from the MasterPure™
Kit. For each kit indicated, a 500-ng aliquot of purified yeast DNA was
analyzed by pulse-field gel electrophoresis on a 1% agarose gel. The gel was
stained with ethidium bromide. The majority of DNA isolated with the MasterPure
Kit was estimated to be in the 40- to 50-kb size range, while degradation
to smaller fragments was observed with other kits. Lane M, lambda DNA ladder;
