how dna extraction kits work in the lab bitesize bio

at bitesize bio we share a lot of troubleshooting tips for rna and genomic dna extraction because almost everything we do in molecular biology requires nucleic acid isolation as the very first step. these days most labs use commercial dna extraction kits based on spin column technology. spin columns contain a silica resin that selectively binds dna (or rna) depending on salt conditions and
