Scientists have been playing with nucleic acids for decades. Now, with so many newly discovered molecules to explore--no longer just genomic DNA and mRNA but mitochondrial DNA, microRNA, small interfering RNA--companies and even individual researchers are coming up with newer and better ways to purify and store nucleic acids for various downstream applications. And some even have technologies that preclude the need for purification altogether.
