ESA Offers Laboratory Application Notes
News Nov 01, 2005
ESA Biosciences, Inc., has produced several application notes demonstrating the use of its Corona® Charged Aerosol Detector with HPLC for chemical analysis.
The notes cover applications involving antibiotics, carbohydrates, carboxilic acids, glycerol, impurity testing, lipids and peptides. The Corona provides response independent of structure, wide dynamic range and low nanogram sensitivity in a detector that is easy to install and use.
“The need for universal HPLC detection in analytical laboratories is widespread,” said John Christensen, ESA Biosciences Vice President.
“While several detection technologies are currently being used, there is significant room for improvement in performance characteristics. To help address the many challenges of universal detection, we have the developed the Corona technology to make life easier and more effective for analytical scientists.”
According to ESA, the Corona CAD’s many benefits include: high sensitivity (low ng limits of detection), consistent response factors not dependent on analyte properties, broad and useful dynamic range (four orders of magnitude: ng - lg quantities), excellent reproducibility, and broad applicability.
Analytical Tool Predicts Disease-Causing GenesNews
Predicting genes that can cause disease due to the production of truncated or altered proteins that take on a new or different function, rather than those that lose their function, is now possible thanks to an international team of researchers that has developed a new analytical tool to effectively and efficiently predict such candidate genes.
‘Good Cholesterol’ May Not Always be Good for Postmenopausal WomenNews
Postmenopausal factors may have an impact on the heart-protective qualities of high-density lipoproteins (HDL) – also known as ‘good cholesterol’ – according to a study led by researchers in the University of Pittsburgh Graduate School of Public Health.READ MORE
What Makes Good Brain Proteins Turn Bad?News
The protein FUS is implicated in two neurodegenerative diseases: amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Using a newly developed fruit fly model, researchers have zoomed in on the protein structure of FUS to gain more insight into how it causes neuronal toxicity and disease.
