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.

Is semaglutide use during breastfeeding safe?

Researchers found no detectable levels of semaglutide in breast milk, suggesting minimal risk to breastfed infants, but highlighted the need for monitoring maternal nutrition and milk production.

New analytical method for identifying cancer cell targets

What are the characteristics of a cancer cell that are recognized by the immune system? Knowledge of the potential target structures for the immune cells is a basic prerequisite for the development of personalized cancer immunotherapies. Scientists from the German Cancer Research Center (DKFZ) and the NCT Heidelberg are publishing a highly sensitive method based on mass spectroscopy to identify such tumor-specific "neoepitopes". The analytical method is designed to detect these low-abundance protein fragments and requires minimal amounts of sample material.

The surprising role of RNA in immune interactions

In a groundbreaking exploration of cell surface biology, Ryan Flynn has uncovered a surprising role for RNA outside the confines of the cell. Flynn's research, which focuses on the biology of cell surface RNA, led to the discovery that certain RNAs are chemically linked to glycans - complex carbohydrate polymers found on the cell surface.

Uncovering hidden drug benefits through protein mapping

Fewer side effects, improved chances of healing: the goal of precision medicine is to provide patients with the most individualized treatment possible. This requires a precise understanding of what is happening at the cellular level. For the first time, researchers at the Technical University of Munich (TUM) have now succeeded in mapping the interactions of 144 active substances with around 8,000 proteins. The results could help to identify previously unknown potential benefits of existing drugs.
