Abstract: | A simple and rapid procedure for the preparation of yeast and fungal DNA samples useful in PCR amplification was developed. The DNA was purified from proteins, lipids, polysaccharides, and other impurities by high-temperature extraction (in a boiling water bath) with buffer solutions containing chaotropic salts. Under these conditions, yeast and fungal cell envelopes remain unbroken and retain the original DNA and RNA that could be used for direct PCR amplification. We called the proposed PCR technique as the PCR using DNA-containing cell envelopes. |
