MtoZ Biolabs provides Biomarker Proteomics Solutions that use high-resolution mass spectrometry to discover, verify, and quantify protein biomarkers in tissues and biofluids. Our services support applications from early discovery research to preclinical translational studies across oncology, neurology, immunology, cardiovascular disease, metabolic disorders, and more.
What Is Biomarker Proteomics?
Biomarkers are measurable biological indicators that reflect normal physiology, disease processes, or responses to therapy. They can be used to aid diagnosis, stratify patients, monitor disease progression, evaluate drug safety, and guide treatment decisions across a wide range of therapeutic areas. Biomarker proteomics focuses specifically on protein based biomarkers, using high resolution mass spectrometry to profile protein abundance, post translational modifications, and pathway level changes in tissues and biofluids. Because proteins are the direct functional molecules in cells, protein biomarkers often provide a closer link to mechanism of action, target engagement, and clinical outcome than nucleic acid based readouts.
Biomarker proteomics solutions integrate discovery scale proteome profiling with targeted, quantitative follow up of selected candidates. By moving systematically from broad protein surveys to focused validation panels, these solutions help researchers identify robust, reproducible markers that can support clinical development, precision medicine, and translational research.
Biomarker Proteomics Services at MtoZ Biolabs
MtoZ Biolabs' biomarker proteomics solutions combine discovery scale DIA-based proteomics with targeted quantitative verification. Using high resolution LC-MS/MS platforms, we can profile thousands of proteins per sample, identify significantly regulated candidates with robust statistics, and refine them into focused biomarker panels suitable for research and translational applications. Candidate markers are then followed up using targeted proteomics strategies such as PRM, SRM, or targeted DIA to achieve precise relative or absolute quantification across large sample sets.
You only need to describe your study objectives and submit your samples. MtoZ Biolabs manages the entire workflow, including protein extraction, digestion, peptide separation, LC-MS acquisition, data processing, and bioinformatics interpretation, delivering results that are ready for downstream biological and clinical evaluation.
Our biomarker proteomics services include:
💠Tissue Biomarker Discovery Solutions
Proteomic profiling of frozen or FFPE tissues, biopsies, xenografts, and animal models to identify protein signatures linked to disease mechanisms, prognosis, and therapeutic response.
💠Biofluid Biomarker Discovery Solutions
In depth analysis of plasma, serum, urine, cerebrospinal fluid, saliva, and other biofluids to uncover minimally invasive protein biomarkers suitable for early detection, patient stratification, and treatment monitoring.
