Electrophoresis is the migration of charged particles or molecules in an electric field. This occurs when the substances are in aqueous solution. The speed of migration is dependent on the applied electric field strength and the charges of the molecules. Thus, differently charged molecules will form individual zones while they migrate. In order to keep diffusion of the zones to a minimum, elect...

We determined characteristics of Salmonella enterica pulsed-field gel electrophoresis clusters that predict their being solved (i.e., that result in identification of a confirmed outbreak). Clusters were investigated by the Minnesota Department of Health by using a dynamic iterative model. During 2001-2007, a total of 43 (12.5%) of 344 clusters were solved. Clusters of ≥4 isolates were more lik...

Cell polarity can be influenced by an electric field, but the mechanisms behind this response are poorly understood. A new paper shows that fission yeast cells change their direction of growth in an external electric field and suggests mechanisms based on the cortical pH gradient and on electrophoresis of membrane proteins.

In the present study, 30 lactic acid bacteria (LAB) strains were isolated from Anbaris, a traditional fermented dairy product manufactured in rural villages of Lebanon goat milk with distinct sharp taste, and identified as members Lactobacillus genus. Among these strains, twelve showed potential probiotic characteristics bile tolerance, angiotensin-converting enzyme (ACE) inhibitory activity, a...
