If tissue stored at Temperature-80 °C , place in Temperature-20 °C for at least Duration04:00:00 or DurationOvernight prior to homogenization.

Weigh tissue out in mg.
Add in 10 volumes of 1X TNE (e.g. Amount10 µL of TNE per Amount1 mg of tissue).
Either by mechanical (Dounce) or homogenizer machine, homogenize tissue gently and TemperatureOn ice .

This is TNE crude lysate (no detergents).
Add equal volume of 1xTNE +1% SDS, 0.5% NP-40, and 0.5% Doc (Complete TNE).
Sonicate at Temperature40 °C (3 pulses: 10s On/2s Off at 20% amplitude).
Boil (Duration00:10:00 ).


Note
*STOPPING Point: Sample should be in “Complete TNE”. Make sure to sonicate and boil prior storage*.
