Protein Purifier Could Help Pharmaceutical Industry Save Money
2012-05-02 03:33:21

Two Michigan State University researchers have invented a protein purifier that could help pharmaceutical companies save time and money. The details of the invention, which appear in a recent issue of the journal Langmuir, demonstrate that MSU chemists Merlin Bruening and Greg Baker´s high-performance membranes are highly suitable for protein purification, a crucial step in the development of some new drugs. Purifying proteins, the process of isolating a single, desired protein...

Reliably quantitate protein with one of AMRESCO´s newest proteomics products, the BCS Assay. Solon, OH (PRWEB) April 29, 2012 Obtaining quality protein samples and quantifying them are essential first steps in proteomics-based research. Proteins may be isolated from any number of tissue or cell types, each likely to require individually optimized extraction methods and buffers that contain various chemicals, including salts and detergents. The varied buffer compositions influence...

New York University biologists have discovered new mechanisms that control how proteins are expressed in different regions of embryos, while also shedding additional insight into how physical traits are arranged in body plans. The researchers investigated a specific theory–morphogen theory, which posits that proteins controlling traits are arranged as gradients, with different amounts of proteins activating genes to create specified physical features. This theory was first put forth...

Protein design is technique that is increasingly valuable to a variety of fields, from biochemistry to therapeutics to materials engineering. University of Pennsylvania chemists have taken this kind of design a step further; using computational methods, they have created the first custom-designed protein crystal. Picking an ambitious design target with challenging features, the researchers´ success bodes well for the technique´s use in better understanding proteins´ makeup...

University of California, San Diego scientists have used powerful computational tools and laboratory tests to discover new support for a once-marginalized theory about the underlying cause of Parkinson´s disease. The new results conflict with an older theory that insoluble intracellular fibrils called amyloids cause Parkinson´s disease and other neurodegenerative diseases. Instead, the new findings provide a step-by-step explanation of how a “protein-run-amok”...

An international team of researchers has reported a new understanding of a little-known process that happens in virtually every cell of our bodies. Protein folding is the process by which not-yet folded chains of amino acids assume their specific shapes, hence taking on their specific functions. These functions vary widely: In the human body, proteins fold to become muscles, hormones, enzymes, and various other components. "This protein folding process is still a big mystery," said UC...

Tiny pores, or channels, embedded in cell membranes are critical to the healthy functioning of cells. Charged atoms, or ions, move through these channels to generate the electrical signals that allow cells to communicate with one another. New research at Washington University School of Medicine in St. Louis unveils some of the inner workings of certain channels involved in regulating electrical signals in nerve cells, relaxing muscle cells and “tuning” hair cells in the inner...

University of Illinois scientists report that soy protein may significantly reduce fat accumulation and triglycerides in the livers of obese persons. And they've discovered why it happens: soy restores partial function of that organ's key signaling pathway. "Almost a third of American adults have fatty liver disease, many of them without symptoms. Obesity is a key risk factor for this condition, which can lead to liver failure," said Hong Chen, a U of I assistant professor of food science...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
