NucleoMag Blood kits are designed for rapid, parallel purification of genomic DNA from whole blood in 96- or 24-well formats. After lysis of blood cells, genomic DNA is selectively bound to the NucleoMag B-Beads. Contaminants are washed away and the DNA can be eluted from the beads under low-salt conditions. Since the magnetic bead technology provides a closed system (no transfer of sample from one well to another is necessary during the preparation), the risk of cross-contamination is reduced.
