Molecular Assay Development
Molecular Assay Development involves designing, optimizing, and validating analytical methods that detect, quantify, or characterize nucleic acids, proteins, biomarkers, pathogens, and molecular signatures with high sensitivity and specificity. These assays support applications in diagnostics, therapeutics, biomaterials testing, medical devices, pharmaceuticals, microbiology, and biotechnology research.
Whether measuring gene expression, identifying microbial contamination, analyzing degradation markers, verifying biological response, or quantifying molecular interactions, well-designed molecular assays are essential for reliable data and regulatory compliance.
Materials Metric provides fully integrated assay development, optimization, and analytical validation services, tailored to the scientific, regulatory, and performance needs of each project.
