Optimization of cell disruption in the MM 400. Using a bead size range from 0.75 to 1 mm results in highest protein concentration (left); the protein concentration is influenced by the number of beads (right). In another method, the process of yeast cell disruption performed using the MM 400 was compared with ultrasonification.

Cell Disruption - an overview | ScienceDirect Topics

Cell disruption can be brought about by a high-speed bead mill, consisting of a series of rotating discs and a charge of glass ballotini (Figure 2).The cell suspension is agitated at a very high speed. The mill chamber is almost full of grinding beads during operation, with the optimum concentration of ballotini usually being 70–90% of the volume of the chamber.

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.

Use of bead mills - London South Bank University

When cell suspensions are agitated in the presence of small steel or glass beads (usually 0.2 -.1.0 mm diameter) they are broken by the high liquid shear gradients and collision with the beads. The rate and effectiveness of enzyme release can be modified by changing the rates of agitation and the size of the beads, as well as the dimensions of the equipment.
