The analysis of nuclear DNA extracted from fecal specimens is an important tool in different areas of molecular genetic research reaching from cancer diagnostics (1-3) to population genetic studies (4). Here we describe a short and simple method for the purification of chromosomal DNA that is ready to be used in PCR. Without further subcloning the resulting PCR products can beiised direcdy for heteroduplex analysis, sequencing or other DNA analysing methods.
