Paper Demonstrates New Top-Down Approach for Identifying Low Abundance Biomarkers

A recent article in Proteomics Clinical Applications demonstrates the validity of a new top-down proteomics approach to identifying low-abundance biomarkers in the one percent of serum/plasma proteins known as the deep proteome. Applying this methodology, French researchers identified a potential biomarker that might be used to track a patient’s recovery from a myocardial infarction (heart attack). Specifically, their goal was to develop indicators that would more accurately predict a complex process called “left ventricular remodeling” that occurs in response to heart damage and leads to heart failure.
