Alternate protocol step for bulk beads. Place sample in microcentrifuge tube and add beads to the tube. Use a volume of beads equal to the mass of tissue. NOTE: 100mg ≅ 100μ
Add 0.025mL to 0.6mL buffer (2 volumes of buffer for every volume of sample).
Close the microcentrifuge tubes.
Place tubes into the Bullet Blender®.
Set controls for SPEED 8 and TIME 3 minutes. Press Start.
After the run, remove tubes from the instrument.
Visually inspect samples. If homogenization is unsatisfactory, run for another two minutes at the SPEED 9.
