Hop DNA Isolation
Hop DNA Extraction Protocol
- Obtain an adequate amount of fresh hop leaves and crush them with liquid Nitrogen and a small amount of Carborundum powder (fine 320 grit).
- Assume 90% of mass is water weight.
- Add 3.3ml of buffer per gram of wet (16ml per gram of dried) hop leaves, and incubate for 1 to 4 hours at 60-65C.
- Put 900μl into 6 tubes and add 600μl of 24:1 CHCl3:octanol to each and shake.
- Centrifuge at 5000g for 10 minutes.
Buffer: 100ml: tris/HCl (ph=8.0) 50mM, NaCl 1.8M, EDTA 50mM. Then add 200mg/ml of CTAB and 20 μl/ml 2-mercaptoethanol.
