The iPrep PureLink Kit (Invitrogen Corp., Carlsbad, CA) produces high yields of pure genomic DNA from up to 350 µl of fresh or frozen blood. Designed specifically for use with the iPrep Purification Instrument using Dynabeads Magnetic Separation Technology, the kit yields sufficient DNA for clinical studies or for multiple PCR-based standardized testing assays. It provides reagents in pre-filled cartridges to eliminate contamination and also includes all tips and tubes needed to isolate DNA from blood samples in just 30 minutes.
