title: [Rapid extraction of MtDNA from Cryptococcus neoformans and examined by electronic microscopy].
abstract: Cryptococcus neoformans may be grown to the exponential phase,are broken by a combination of NovoZym234 and mechanical means,and mitochondrial DNA was extracted from DNaseI-treated mitochondrial preparation by differential centrifugation. Three pellets, including yeast cell, protoplasts, mitochondrial, were examined by transmission electronic microscopy. The resulting mtDNA is sufficiently pure for restriction endonucleases analysis and PCR in further studying. A rapid and effective method for the preparation of the mtDNA of C.neoformans was established.
