HiPurA® Water DNA Purification Kit (without enrichment) provides a fast and easy method for purification of total DNA using the miniprep spin columns. It is is based on the advanced silica binding principle presented in a microspin format facilitating the binding, washing and elution steps thus enabling multiple samples to be processed simultaneously. It comprises of three steps viz. adsorption of DNA to the membrane, removal of residual contaminants and elution of pure genomic DNA. In this technique, the water sample is passed through a 0.22 µm filter membrane and the micro-organisms present in the water are trapped. The membrane is then placed in a Hi-Water Bead tube for thorough lysis in presence of a Lysis Buffer. Concentration of DNA can be estimated by agarose gel electrophoresis.
