Secreted beta-galactosidase from a Flavobacterium sp. isolated from a low-temperature environment.

The bacterial strain Flavobacterium sp. 4214 isolated from Greenland was found to express beta-galactosidase (EC 3.2.

Hydrodynamic guiding for addressing subsets of immobilized cells and molecules in microfluidic systems.

Background: The interest in microfluidics and surface patterning is increasing as the use of these technologies in diverse biomedical applications is substantiated. Controlled molecular and cellular surface patterning is a costly and time-consuming process. Methods for keeping multiple separate experimental conditions on a patterned area are, therefore, needed to amplify the amount of biological information that can be retrieved from a patterned surface area.
