PTM Biosciences is pioneering proteomics-based personalized medicine. We utilize innovative technology conceived at the Harvard Medical School by Yifat Merbl, PhD, and focus on protein activity and function, which are most relevant to disease phenotype. We analyze liquid biopsies and tissue samples and generate novel data, which captures the activity of modifying enzymes (e.g. E3 ligases) and allows the discovery of novel biomarkers and therapeutic targets.
