Giant Liposomes Make Tiny Test Tubes

November 17, 2003 8:56 am | Articles | Comments

by Elizabeth Tolchin Scientists have found a new technique for performing ultra-small-volume chemical reactions. The technique uses giant (cell-sized) liposomes as nanovials and an ultraviolet laser pulse to fuse them together. The approach may be useful for faster, cheaper identification of new pharmaceuticals and for studying cellular-level processes.

Bacteria Cranks Up Mutation Apparatus When Starved 11/14/03

November 14, 2003 11:44 am | Articles | Comments

by Pam Holland-Moritz Starving Escherichia coli bacteria appears to increase their ability to mutate and adapt to the situation. Spontaneous mutations are quite normal in bacteria under environmental stress, but a report published in Molecular Microbiology [J. C. Layton, P. L. Foster, vol. 50, pp. 549-561 (2003)] showed that some bacteria increase genetic mutations in response to nutrient restriction.

Confocal Microscope Systems - A Comparison Of Technologies

November 14, 2003 4:34 am | Articles | Comments

Confocal microscopy offers a number of advantages when compared with traditional widefield optical microscopy. Confocal systems occlude out-of-focus light, vastly improving imaging contrast.

Protein Disulfide-Isomerase Accelerates Protein Refolding

November 13, 2003 10:18 am | Articles | Comments

Protein disulfide-isomerase (PDI) is an enzyme that in mammalian cells catalyzes post-translational thiol-disulfide exchange reactions in expressed proteins. Such exchanges lead to refolding of the protein and greatest overall protein stability. Protein folding can particularly be a problem for E.
