Cell Disruption: Sonication vs. Homogenization

Bead-based homogenization uses plastic or metal beads combined with high-speed shaking to create shearing forces. This technique is well-suited to whole animal, insect (e.g., Drosophila melanogaster) or plant specimens, which requires disruption of sturdy cell walls.A drawback of bead-based disruption is that it requires the proper selection of bead material and diameter.
