To obtain high-quality, purified nucleic acids, scientists can use several different methods, including phenol-chloroform extraction, cesium chloride/ethidium bromide (CsCl/EtBr) gradient ...

RNA and DNA extraction kits take formalin-fixed tissue samples by storm, enabling superior quality and yields. Researchers using standard extraction protocols that heat samples to eliminate ...

When you think about scientific research, you probably envision a sterile room that houses gleaming beakers, rows of pipettes and centrifuges. But what if you could house a lab on a chip? Call it the ...

Swedish Researchers Extract Ancient Scandinavians' DNA From a 10,000-Year-Old 'Chewing Gum' Advanced technology has finally allowed experts to analyze DNA from a chewed-up birch bark in Sweden, ...

The ability to extract trace bits of DNA from soil, water, and even air is revolutionizing science. But it's not foolproof. In the late 1980s, at a federal research facility in Pensacola, Florida, ...

DNA extraction is a very important part of medical science; it helps us study the genetics of new diseases and scientists can then make diagnostics and drugs to fight against them. This experiment can ...

We use a simple chemical extraction process on 25 pounds of strawberries and collect the visible strands of pure DNA the fruit produces.
