UT-Austin, Southwestern U Developing New Biomarker Screening Technology

Researchers at The University of Texas, Austin and Southwestern University will use a $730,000 grant from the National Institutes of Health to develop a new method for rapidly screening blood samples for protein biomarkers, UT-Austin said last week.

The three-stage screening method will involve using a chip with capture agents that bind to specific compounds in a blood sample, an ultraviolet light to sever those chemical bonds, and an electrospray that transfers the compounds into a mass spectrometer for analysis.

The mass spectrometry data could then be used to measure the presence and quality of different proteins “on a scale, and with a speed, that wasn’t possible before,” Jennifer Brodbelt, a professor at UT-Austin and principal investigator on the project, said in a statement.
