Realtime Stain from Biophoretics is a single step coomassie like pre-electrophoresis protein stain that allows visualizing the separation as it occurs; in real time. The stain irreversibly binds amine groups coloring the proteins deep blue with little to no gel background; providing detection sensitivity as low as 50ng.
Just try sugar-coating this: The World Health Organization says your daily sugar intake should be just 5 percent of your total calories — half of what the agency previously recommended, according to new draft guidelines published Wednesday. After a review of about 9,000 studies, WHO's expert...
Sounding an alarm about the growing threat of superbugs, the Obama administration is proposing a jump in spending to fight antibiotic-resistant germs in hospitals. In Tuesday's budget, the CDC is seeking $30 million to open specialized laboratories in five parts of the country to help local hospitals more quickly diagnose and combat drug-resistant infections, said CDC director Dr. Tom Frieden.
At least two camps have formed in the “breast cancer stem cell” world. One camp believes most cancers may come from stem cells—or stem-like progenitors—gone awry. Others agree cancers can be most virulent when reaching a stem cell-like state—but believe they may come from both stem cells and mature cells gone awry.
The Attune Acoustic Focusing Flow Cytometer from Life Technologies Corporation is designed to deliver higher sensitivity. The cytometer can maintain precise alignment, even at sample rates of up to 1 mL/minute. Alternatively, the cytometer has a slower rate to collect more photons when analyzing dim signals, which translates to better separation and better clarity of results.
Researchers have revived a giant virus more than 30,000 years old, recovered from the permafrost of northeast Siberia. The virus poses no threat to people. Although it is considered a giant when compared to other viruses, it is microscopic and infects amoebas.
Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in...
In a new study that could help doctors extend the lives of patients awaiting liver transplants, a Rice University-led team of researchers examined the metabolic breakdown that takes place in liver cells during late-stage cirrhosis and found clues that suggest new treatments to delay liver failure.
A drug that unleashes the immune system to attack cancer can produce lasting remissions and hold the disease in check – for more than two years, in some cases – in many patients with advanced melanoma, according to a new study. The study provides the longest-term look so far at how melanoma patients have fared since receiving the drug, nivolumab, in a Phase 1 clinical trial.
Veterans exposed to explosions who do not report symptoms of traumatic brain injury (TBI) may still have damage to the brain's white matter comparable to veterans with TBI, according to researchers at Duke Medicine and the U.S. Department of Veterans Affairs. The findings suggest that a lack of clear TBI symptoms following an explosion may not accurately reflect the extent of brain injury.
In the largest, most comprehensive, nationwide study to examine the prevalence of allergies from early childhood to old age, scientists from the National Institutes of Health report that allergy prevalence is the same across different regions of the United States, except in children 5 years and younger.
A of researchers has found evidence that photosensitizing a virus's membrane covering can inhibit its ability to enter cells and potentially lead to the development of stronger, cheaper medications to fight a host of tough viruses. The UCLA AIDS Institute study is part of ongoing research on a compound called LJ001, a "broad-spectrum" antiviral that can attack a wide range of microbes.
In space, things don’t always behave the way we expect them to. In the case of cancer, researchers have found that this is a good thing: some tumors seem to be much less aggressive in the microgravity environment of space compared to their behavior on Earth.
Johns Hopkins researchers report that people with chronic insomnia show more plasticity and activity than good sleepers in the part of the brain that controls movement. They found that the motor cortex in those with chronic insomnia was more adaptable to change - more plastic - than in a group of good sleepers. They also found more "excitability" among neurons in the same region of the brain among those with chronic insomnia.
Scientists at The Scripps Research Institute (TSRI) have invented small-molecule folding probes that enable them to quantify functional, normally folded and disease-associated misfolded conformations (shapes) of a protein-of-interest in cells under different conditions.
