Abstract
The isolation of DNA from biological samples is a crucial step in the process of DNA-based molecular biological assays. In this study, we present a simple method to extract and purify genomic DNA from different sample types (standard cyanobacteria, cyanobacteria in water samples and leaves of bamboo plants) which would be suitable for any molecular analyses. In this method, cyanobacteria are lysed by three sequential freezing and heating followed by enzymatic treatment with lysozyme and proteinase K. The extraction and purification of DNA was achieved with the lysing and nuclease inactivating properties of the chaotropic agent guanidium isothiocyanate and the nucleic acid binding properties of silica particles. The DNA extraction method yielded high quality reproducible DNA. The technique described here is a rapid, robust and cost effective method suitable for the extraction of DNA from any source for routine molecular biological assays.
