WebEthidium bromide can be added to the samples if desired. NorthernMax-Gly Sample Loading Dye An improved formulation used for RNA sample denaturation in any glyoxal gel protocol. The volume ratio of solution to sample is lower than in published protocols, so sample precipitation prior to gel loading is usually not required. WebThe polymerase chain reaction (PCR) is a relatively simple technique that amplifies a DNA template to produce specific DNA fragments in vitro. Traditional methods of cloning a DNA sequence into a vector and replicating it in a living cell often require days or weeks of work, but amplification of DNA sequences by PCR requires only hours.
