Description:
Blood DNA Preparation Kit is designed for convenient and fast isolation of genomic DNA from whole blood samples. The solution based system minimizes DNA fragmentation that may be problematic in spin-column / filtration based methods. Because phenol or chloroform is not used it is safe and does not produce any harmful waste.
Solution based genomic DNA purification kits guarantee minimal DNA fragmentation and yield DNA sized up to 150 kb.

Expected yield:
Yields of genomic DNA will vary from sample to sample depending on the amount, quality and type of material processed. An amount of approx. 30-50 μg purified DNA can be expected per preparation of 300 μl whole blood. Upscaling of the preparation by a factor of 10 is easily possible if larger amounts of DNA are required.

1 Cell Lysis:

  • Pipet 900 μl RBC Lysis Solution to a 1.5 ml microtube, add 300 μl of whole blood or bone marrow and invert 10 times.
  • Incubate for 3 min at room temperature with occasional inversion. Please Note: For fresh blood collected within 1 hour before preparation increase the incubation time to 10 min to ensure complete red blood cell lysis.
  • Centrifuge for 30 sec at 15,000 g.
  • Remove the supernatant with a pipet leaving behind the visible cell pellet. Make sure not to exceed 20 μl of residual liquid. This is a critical point for effective protein and DNA precipitation in the following steps.
  • Vortex the tube vigorously for 10 sec to resuspend the white cells in the residual liquid. The white cell pellet should be completely resuspended.
  • Add 300 μl Cell Lysis Solution to the resuspended cells and pipet up and down to lyse the cells until no clumps are visible.
  • For heparin-treated blood, heat the white cell pellet for 10 min at 65 °C to facilitate lysis.


2 Protein Precipitation:

  • Add 100 μl Protein Precipitation Solution to the cell lysate.
  • Vortex vigorously for 20 seconds to mix well. Tiny particles of precipitated protein (no clumps) should be visible.
  • Centrifuge at 15,000 g for 1 min.
  • The precipitated proteins should form a tight, dark pellet. If the protein pellet is not tight, repeat vortexing, followed by incubation on ice for 5 min and centrifuge again.


3 DNA Precipitation:

  • Pipet 300 μl Isopropanol >99 % into a clean 1.5 ml microtube and add the supernatant.
  • Mix the sample by inverting gently for 1 min.
  • Centrifuge at 15,000 g for 1 min. DNA should be visible as a small white pellet.
  • Discard the supernatant and drain tube briefly on clean absorbent paper.
  • Add 500 μl Washing Buffer and invert the tube several times to wash the DNA pellet.
  • Centrifuge at 15,000 g for 1 min.
  • Carefully discard the ethanol and dry at room temperature for about 10 to 15 min.


4 DNA Hydration:

  • Add 50-100 μl DNA Hydration Solution.
  • Vortex 5 sec at medium speed to mix.
  • Incubate the sample at 65 °C for 30 min to accelerate rehydration.
  • Store DNA at 4 °C. For long time storage, place sample at -20 °C or -80 °C.
