Electrophoresis

US scientists have used 2D gel electrophoresis to analyse the proteins in pressure ulcer wound fluid, in order to find early indicators and biomarkers for this condition.

While-you-wait DNA profiles should soon be available for anyone arrested by the police, thanks to a new microfluidic device developed by British and US scientists.

Chinese material scientists have developed a new dynamic coating for capillary electrophoresis, which prevents proteins sticking to capillary walls.

In order to discover more about the acute inflammation caused by ulcerative colitis, Japanese scientists used 2D fluorescence difference gel electrophoresis to analyse the proteins expressed in the intestines of mice.

To control the movement of individual droplets and their molecular contents, all you need are different size beams of light, say US scientists.

Using two different forms of gel electrophoresis, Spanish scientists have analysed the proteomes of two species of reptile: a turtle and an iguana.

Australian scientists have conducted the first 2D gel electrophoresis study using sequential dyes to analyse phospho-, glyco- and total tear protein profiles, discovering a novel tear protein in the process.

A team of US scientists has developed a method for locating exactly where a comet will be at any given point, but only if it's made of DNA.

Using gel electrophoresis and peptide mass fingerprinting, Portuguese scientists investigated the effects of food restriction on gastrocnemius muscle protein expression in New Zealand White (meat producing) and wild rabbits.

Using PCR and microchip electrophoresis, Korean scientists have developed a novel method for diagnosing cattle infected with the bacterium <i>Anaplasma phagocytophilum</i>, which can also cause disease in humans.

Self-assembling nanoparticle 'walls' are just as good at separating DNA strands as polymer gels, say Canadian scientists, but for the best results the gaps in the walls should be as small as possible.

This review looks at the various electrophoresis techniques that are available for studying biomolecules like proteins, including 2D electrophoresis, isoelectric focusing, isotachophoresis and microchip electrophoresis.

British scientists have shown that dielectrophoresis - the movement of particles in non-uniform electric fields - can be used to create engineered skin with artificial placodes of different sizes and shapes, in different spatial patterns.

Conventional DNA fingerprinting can distinguish between individuals and identify family ties, but now US scientists have produced a new version that can also accurately determine gender and ethnicity.

An international team of researchers has shown that transient isotachophoresis can be used to focus anionic micelles prior to micellar electrokinetic chromatography.

To make it easier to extract proteins after 2D gel electrophoreis, German scientists have developed a novel partly-reversible gel system, in which the gel matrix can be conditionally cleaved to increase the pore diameters.

By shifting the balance of power between electrophoresis and electro-osmosis, Dutch and US chemists have managed to concentrate DNA into bands just 10µm wide.

This review describes proteomic approaches, such as gel electrophoresis, that have been used to investigate diverse biological questions in model and non-model fish species, incuding questions about physiology and developmental biology.

Using lectin affinity electrophoresis, French scientists have investigated the use of serum alkaline phosphatase isoenzymes as markers of breast cancer.

The migration of particles along a temperature gradient, known as thermophoresis, could allow biomolecules to be analysed entirely within biological fluids such as blood serum, say German physicists.
