Instructions
Using the Shredder-Tube Cap Tool, a serrated [[Shredder-Ram}} is inserted into one of the Shredder-Tubes or Shredder-Tubes\Metal, pressing the sample between the serratged surface of the Shredder-Ram and the lysis disk of the tube. Ice-cold mitochondrial medium (200-700 Β΅l MiR06 or MiR07) 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 O2k-Chamber.
Advantages of the PBI-Shredder
- Low shear mechanical device for gentle, rapid and safe disruption of tissues;
- Three position lever for setting reproducible force to the sample during the shredding process;
- Gentle enough for isolating intact, functional mitochondria;
- Powerful enough to rapidly break apart difficult samples;
- Standardized preparations of high quality;
- Enables reproducible results;
- Easy handling, especially for beginners;
- Processing containers:
- > Standard tubes for ambient pressure processing
- > Closed containers help to ensure safety throughout the entire sample preparation process;
- > Excellent for collection, storage, transport and processing
- High quality of functional mitochondria is obtained from skeletal muscel and kidney as evaluated by high resolution respirometry:
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 difficulities in reproducing experimental results over time and across laboratories
- During manual homogenization it is difficult to know when sufficient tissue disruption has occured - overhomogenization!
- The current protocols rely on Dounce, Potter-Elvehjem, and rotor/stator shearing homogenization:
