Mouse Tail Genomic DNA Isolation Protocol(1)

Note: Genomic DNA is fragile. High molecular weight DNA is sheared easily by mechanical forces. Use suitable large-bore pipet tips or equipment when pipetting genomic DNA. Do not vortex solutions containing genomic DNA.
  1. Place a 1 cm tail sample into a 1.5 ml microcentrifuge tube; this may be stored at 20C. To minimize possible cross-contamination, do not mince the sample. Add 700 l Tail Buffer (50 mM Tris-HCl, pH 8.0, 100 mM EDTA, 100 mM NaCl, 1% SDS) to the sample.
  2. Add 35 l 10 mg/ml Proteinase K to the sample and mix briefly.
  3. Incubate at 5560C overnight with mixing. This step should result in the complete solubilization of the tail fragment. In the case of incomplete digestion, more Proteinase K can be added and the samples incubated for several more hours.
  4. Add 20 l 10 mg/ml RNase A (DNase-free) to the sample. Mix briefly and incubate at 37C for 12 hours.
  5. Transfer entire solution to a pre-spun (1500 x g for 12 minutes) PLG 2 ml Heavy tube.
  6. Add 0.5 ml Phenol-Chloroform-Isoamyl Alcohol (PCI, 25:24:1) to the sample in the PLG 2 ml tube and mix well by repeated inversion. Do not vortex.
  7. Centrifuge at full speed (12,000 x g or greater) for 5 minutes in a microcentrifuge, then carefully transfer the resultant aqueous phase to a fresh pre-spun PLG 2 ml Heavy tube.
  8. Add 0.5 ml Chloroform-Isoamyl Alcohol (CI, 24:1) to the sample in the PLG 2 ml tube and mix well by repeated inversion. Do not vortex.
  9. Centrifuge at full speed (12,000 x g or greater) for 5 minutes in a microcentrifuge, the n carefully transfer resultant aqueous phase to a fresh microcentrifuge tube.
  10. Fill sample-containing tube with 100% Isopropanol and mix thoroughly by repeated inversion. Do not vortex. A visible DNA precipitate should form. Proceed immediately to step 11.
  11. Recover DNA precipitate by touching it to a heat-sealed glass micropipette tip or by lifting the DNA with a yellow pipette tip and partial suction from a pipettor. Transfer the DNA to a 1.5 ml microcentrifuge tube containing 70% Ethanol. If DNA is not stringy, pellet by a brief, low speed centrifugation.
  12. Wash DNA with the 70% Ethanol, then wash twice with 95% Ethanol.
  13. Allow DNA to partially dry and then either transfer the DNA to a microcentrifuge tube containing 400 l TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0) or add 400 l TE to the DNA in the tube. Do not vortex or re-pipet to resuspend DNA.
  14. Resolubilize the DNA overnight (e.g. by rotation at 3060 rpm). Resolubilization may be facilitated by heating the sample at 50C.
