Study reveals strain of V. cholerae in Haiti cholera outbreak originated from single source

The strain of cholera that has sickened thousands in Haiti came from a single source and was not repeatedly introduced to the island over the past three years as some have thought, according to a new study published in mBio-, the online open-access journal of the American Society for Microbiology.

Study identifies 29 potential DS biomarker proteins in maternal serum

Prenatal screening for Down syndrome (DS) is still in need of improvement. Perinatal medicine experts have worked hard to find new biomarkers for screening of DS. Dr. Shi he Shao and his co-investigators, from Jiangsu University and Changzhou Woman and Children Health Hospital, report in the May 2012 issue of Experimental Biology and Medicine that they have successfully identified twenty-nine differentially expressed proteins in maternal serum from pregnancies carrying DS fetuses with proteomic approaches.

June Cold Spring Harbor Protocols features electrophoresis in RNA analysis and avian embryos

Gel electrophoresis is one of the most important and frequently used techniques in RNA analysis. Electrophoresis is used for RNA detection, quantification, purification by size and quality assessment. Gels are involved in a wide variety of methods including northern blotting, primer extension, footprinting and analyzing processing reactions. The two most common types of gels are polyacrylamide and agarose.

Researchers develop new electrophoretic method for detecting MIRCERA and EPO in blood

Austrian researchers have successfully developed a new electrophoretic method for detecting MIRCERA® and other erythropoietins (EPO) in the blood. The technique, using SARCOSYL-PAGE, has specifically enhanced sensitivity for MIRCERA, but does not alter the performance characteristics of SDS-PAGE for detecting other EPOs.

Precision control of DNA separation using an electric field

An electric voltage can be used to propel DNA molecules through a channel a few nanometers deep, or to stop them in their tracks. In a strong electric field the molecules judder along the channel, while in weaker fields they move more smoothly. This enables DNA fragments to be 'captured' on a chip and separated for analysis.

New insight into radiation damage to DNA

A new technique for assessing the damage radiation causes to DNA indicates that the spatial arrangement of damaged sites, or lesions, is more important than the number of lesions in determining the severity of the damage.
