This is a home made recipe:
Prepare this Lysis buffer (Chip Lysis Buffer):
50 mM Tris, pH around 8.0
10 mM EDTA
Then mix these:
50% of Phenol(pH around 7.8 )/Chloroform
25% of Lysis buffer (Chip Lysis Buffer)
25% of Water
Now you can use it for DNA extraction:
Add 1 ml of that mixture above with pellet of bacteria or cells.
Dissolve bacteria or cells by pipetting up and down.
Keep vials on ice for 10 min.
put vials on vortexer horizontally and vortex for 15 seconds.
Centrifuge >11000 g for 15 min
Add the same volume of Isopropanol and invert several times and stay for 10 min at RT.
Centrifuge again. and wash pellet with 70-75 % Ethanol.
You can increase the SDS percentage to facilitate Cell and tissue disrupting.
