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:
