In this article, Professor Forest White, Department of
Biological Engineering at MIT, and Dr Lauren Stopfer, Scientist at BioNTech,
present a novel assay approach for the rapid, reproducible and accurate
identification of potential therapeutic targets using mass spectrometry.
Proteins are key therapeutic targets due to the biochemical
functions they perform within our bodies. As we continue the move to an era of
precision medicine, greater understanding of proteins and protein networks and
their relationships with diseases like cancer enables scientists to better
identify targets for developing new therapeutics.
To fully understand these networks, analytical methods
with high sensitivity, reproducibility and selectivity are needed. One of the
most powerful techniques commonly used to support therapeutic research and
development is mass spectrometry (MS), which is notably being applied to the
characterisation of tyrosine phosphorylation (pTyr).
