Mass Spectrometry News and Research

RSS

Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

New designer steroid discovered in anonymously provided syringe

A previously unknown synthetic "designer" steroid has been identified as tetrahydrogestrinone (THG). Researchers working out of the UCLA Olympic Analytical Laboratory in Los Angeles synthesized and characterized the "New Chemical Entity", and proceeded to develop a rapid and accurate urine detection test for it.

Functional genomics and proteomics may accelerate the discovery of new drugs and therapeutic molecules

Functional genomics and proteomics have been quite successful in identifying functions of potential therapeutic targets such as encoded proteins. In fact, the possibilities of identifying more than 10,000 novel target antigens in the human genome may accelerate the discovery of new drugs and therapeutic molecules.

Mass spectrometry offers promising diagnostic test for sleeping sickness

Around half a million people a year in sub-Saharan Africa are affected by sleeping sickness (human African trypanosomiasis). The disease is fatal in humans if not treated with chemotherapy; however, adverse effects of drug treatment and an increase in drug resistance underline the importance of establishing an accurate diagnostic test for the disease.

Identification of first protein biomarkers to help patients with amyotrophic lateral sclerosis

A University of Pittsburgh pathologist has identified the first protein biomarkers able to diagnose patients with amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease) with near 100 percent accuracy. Before this finding, there were no known diagnostic biomarkers for this neurodegenerative disease.

Using mass spectrometry to diagnose cancers and non-cancerous diseases

Using mass spectrometry, Emory University scientists have identified specific protein fingerprints in the cerebrospinal fluid (CSF) of humans that enable them to differentiate between cancers, both primary and metastatic, and non-cancerous diseases of the central nervous system (CNS).

Protein identification gets a speed boost

But the labor intensity of the procedure is now a thing of the past for researchers in the Oregon Health & Science University School of Medicine. The Proteomics Shared Resource, an unassuming but state-of-the-art lab on the fifth floor of OHSU's Medical Research Building, can process more than three times as many protein samples in half a day, and much of it can be done by one person.
