Fast and Cost-effective Extraction of Genomic DNA from blood

MagSi-gDNA blood kit allows fast and cost-effective extraction of genomic DNA from a wide range of sample volumes. The paramagnetic bead-based kit can be used on whole blood samples drawn in EDTA-, citrate- or heparin tubes. Due to the ready to use reagents and simple protocol the kit is easy to use and easy to automate. As a linear volume to volume ratio is used between whole blood sample and reagents, it is possible to use the kit in any situation where genomic DNA out of blood is needed.


  • Suitable for whole blood, drawn in Citrate-, EDTA- or Heparin tubes
  • Reproducible, high yield of DNA – up to 8 μg from 200 μL fresh or frozen whole blood
  • Excellent purity, A260/280 = 1.7-2.0
  • Suitable for many genomic applications including PCR, DNA sequencing and Southern blotting
  • Simple bind-wash-elute procedure
  • Protocol easily adjustable for different sample volumes
  • Manual and automated use
  • Safe sample handling with minimal user input
  • Also suitable for isolation of DNA from saliva, serum/plasma and cultured cells

Easy to automate

  • Compatible with many different automated liquid handling systems (e.g KingFisherTM, PrimaRWS®, PIPETMAX® and JANUS®)
  • Short and easy protocols
  • Suitable for small, medium and high-throughput automation
  • Variable volume sample input possible
