French Press G-M® High Pressure Cell Disruption

A French press is commonly used to break the resilient plasma membrane and cell walls of bacteria and other microorganisms for isolation of proteins and other cellular components. The disruption of cells in a French press generates 'inside-out' membrane vesicles which are required for many in vitro biochemical assays.

A Review on Macroscale and Microscale Cell Lysis Methods

Cells are of two types: eukaryotic (such as mammalian cells) and prokaryotic (such as bacteria). The main difference between these two types is in their structure and organization. Figure 2 illustrates the difference between mammalian cells and bacteria. Mammalian cells have a boundary called cytoplasmic membrane that encloses the …
