DNA extraction using HotShot
Mixing the buffers
Alkaline Buffer (= 25 mM NaOH + 0.2 mM disodium EDTA)
- Premix 10M NaOH:
- 70 ml H₂O + 40g NaOH and adjust to 100 ml
- or
- 17.5 ml H₂O + 10g NaOH and adjust to 25 ml
- To 25 ml of H₂O add:
- 62.5 μl of 10M NaOH
- 10 μl of 0.5 M disodium EDTA
Neutralizing Buffer (40 mM trisHCl)
Mix the following:
- 24 ml of H₂O
- 1 ml of 1M trisHCl
Extraction
- 10–15 μl of alkaline buffer + specimen
- Incubate at 65°C for 18 mins + 98°C for 2 mins
- Add the same amount of neutralizing buffer
