Invitrogen this week introduced its ChargeSwitch-Pro plasmid miniprep kits.
According to the company, the kits apply its latest nucleic acid-purification technology into a spin column format. It added that ChargeSwitch is the only sample preparation method that does not use ethanol or chaotropic salts, which are “two reagents that are known to inhibit enzymatic reactions and present storage, shipping, and handling challenges.”
