Abstract PURPOSE In this study we sought to determine whether a Titin peptide fragment can serve as a clinical biomarker for changes in muscle mass. METHODS Mass spectrometry was used to identify Titin fragment in urine. An antibody against this Titin sequence was raised and used to develop a competitive ELISA assay for measurement in […]
