Broad Institute researchers have used a novel approach to increase our understanding of the immune system as a whole.
When it Comes to Breast Cancer, Common Pigeon is No Bird Brain
If pigeons went to medical school and specialized in pathology or radiology, they’d be pretty good at distinguishing digitized microscope slides and mammograms of normal vs. cancerous breast tissue, a new study has found.
Editing of LIMS Data Made Faster and More Efficient in Matrix Gemini
The latest version of the Matrix Gemini LIMS (Laboratory Information Management System) from Autoscribe Informatics now provides faster and more efficient editing of LIMS data by eliminating the need for a second editing screen.
How a Genetic Locus Protects Adult Blood-Forming Stem Cells
Mammalian imprinted Gtl2 protects adult hematopoietic stem cells by restricting metabolic activity in the cells' mitochondria.
Genetic Basis of Fatal Flu Side Effect Discovered
A group of people with fatal H1N1 flu died after their viral infections triggered a deadly hyperinflammatory disorder in susceptible individuals with gene mutations linked to the overactive immune response, according to a recent study.
New Tech Vastly Improves CRISPR/Cas9 Accuracy
A new CRISPR/Cas9 technology developed by scientists at UMass Medical School is precise enough to surgically edit DNA at nearly any genomic location, while avoiding potentially harmful off-target changes typically seen in standard CRISPR gene editing techniques.

Quantification of Ethylglucuronide in hair by Liquid Chromatography Tandem Mass Spectrometry
Bookmark and Share


Ethanol is converted to acetaldehyde and subsequently to acetic acid by liver enzymes. The traditional approach to assess the extent of alcohol consumption is through blood and urine analysis but unless the blood or urine samples are stored in appropriate specimen containers, with preservatives such as fluoride oxalate, ethanol can be produced as an artifact of bacterial fermentation post collection. This can result in elevated and hence inaccurate ethanol concentrations in these samples which can potentially affect the interpretation of any results obtained.

As ethanol metabolism is independent of dose, blood and urine concentrations can vary widely between individuals, however with hair analysis the use of a 30 pg/mg cut off, as proposed by the Society of Hair Testing (SoHT), can be applied as standard. 

This application note details a rapid, robust, sensitive and specific LC-MS/MS assay for the quantification of ETG, a marker for chronic excessive alcohol consumption, in hair, which has been developed in accordance with ISO17025 standards.
