Silica in a spin column with water and with DNA sample in chaotropic buffer. Spin column-based nucleic acid purification is a solid phase extraction method to quickly purify nucleic acids. This method relies on the fact that nucleic acid will bind to the solid phase of silica under certain conditions.
QIAGEN acquired Digene for US$1.6 billion, furthering QIAGEN in molecular diagnostics by revenue and diagnostics for disease prevention. [ 9 ] In 2009, QIAGEN began building its Personalized Healthcare business through the acquisition of DxS Ltd, in a deal valued at US$95 million [ 10 ] and it acquired SABiosciences Corp. in a deal valued at US ...
The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and ...

Gel extraction kits are available from several major biotech manufacturers for a final cost of approximately 1–2 US$ per sample. Protocols included in these kits generally call for the dissolution of the gel-slice in 3 volumes of chaotropic agent at 50 °C, followed by application of the solution to a spin-column (the DNA remains in the column), a 70% ethanol wash (the DNA remains in the ...
Buffer P2 is a lysis buffer solution produced by Qiagen.It contains 1% sodium dodecyl sulfate (SDS) (w/v) to puncture holes in cellular membranes, and 200mM NaOH.It is used in conjunction with other resuspension buffers and lysis buffers to release DNA from cells, often as part of the alkaline lysis method of purifying plasmid DNA from bacterial cell culture.
