About Us // Targeted Proteomics Biomarker Experts - Protein Biomarker Quantification Services
MRM Proteomics provides advanced proteomics services and kits to the pharmaceutical, biotechnology and diagnostics industries in key areas such as biomarker discovery/validation, clinical studies, diagnostics and toxicology. As a leader in targeted proteomics approaches, we specialize in the highly multiplexed quantitation of >150 protein biomarkers in complex biological samples such as blood, cerebrospinal fluid, urine and other fluids/tissues. Our workflows use Multiple Reaction Monitoring/Mass Spectrometry (MRM/MS) with isotopically-labeled internal standards to achieve unparalleled specificity and sensitivity. The labeled internal standards are called Stable Isotope Standard (SIS) peptide sa they are synthesized using stable isotopes of carbon and nitrogen that are not radioactive. This approach uses minimal sample volumes (20 ul) and does not require depletion of high-abundance proteins.
