:::: Using the [[Shredder-Tube Cap Tool]], a serrated Shredder-Ram is inserted into one of the Shredder-Tubes, pressing the sample between the serrated surface of the Shredder-Ram and the lysis disk of the tube. Ice-cold mitochondrial medium (200-700 µl [[MiR06]] or [[MiR06Cr]]) is then added to the opposite Cap side of the tube, which is closed by a [[Shredder-Screw Cap]], again using the Shredder-Tube Cap Tool.  The filled Shredder-Tube is placed into the pre-cooled Shredder Base, with the Ram side facing downwards, and the SG3 driver is placed onto the Cap. The force setting lever is placed into the position (1-low, 2-medium), and shredding for 20-30 s is sufficient for several different tissues.  The processed homogenate is sampled from the Shredder-Tube by unscrewing the Shredder-Screw Cap using the Shredder-Tube Cap Tool and removing the cap, for transfer of the sample into the [[Oroboros O2k|O2k-Chamber]].
 
 
 
 
== Traditional methods for homogenization ==
::::* Homogenizer-based protocols that require extensive operator experience (highly skilled personnel) to obtain reproducible high-quality preparations.
::::* These methods limit dissemination, impede scale-up, and contribute to difficulties in reproducing experimental results over time and across laboratories.
::::* During manual homogenization it is difficult to know when sufficient tissue disruption has occurred - overhomogenization!
::::* The current protocols rely on Dounce, Potter-Elvehjem, and rotor/stator shearing homogenization:
