Many procedures in molecular biology require the isolation of high quality genomic DNA. This study investigated a new method to extract DNA from Gram-negative, Gram-positive bacteria, Mycobacteria and yeasts. Guanidine thioisocyanate present in DNAzol is capable of binding DNA to silica particle column. Subsequently the silica with adsorbed DNA is washed to remove impurities and the clean DNA eluted in appropriate buffer. Results indicated that the new extraction method is simple and reproducible. This isolation technique is faster and easier to perform than the other conventional extraction methods. Finally the recovered DNA is of high quality and suitable for downstream applications. <br />(African Journal of Biotechnology: 2003 2(8): 251-253)
