DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods.The first isolation of DNA was done in 1869 by Friedrich Miescher. Currently it is a routine procedure in molecular biology or forensic analyses. Breaking the cells open, commonly referred to as cell disruption or cell lysis, to expose the DNA within. 2  This is commonly achieved by chemical and physical methods-blending, grinding or sonicating the sample. 3  Removing membrane lipids by adding a detergent or surfactants which also serves in cell lysis.
The QIAquick Gel Extraction Kit provides spin columns, buffers, and collection tubes for silica-membrane-based purification of DNA fragments from gels (up to 400 mg slices) or enzymatic reactions. DNA ranging from 70 bp to 10 kb is purified using a simple and fast bind-wash-elute procedure and an elution volume of 30â50 Î¼l.
