Experienced in developing, qualifying, and validating biomarker assays


biomarker feature ptau217 - Biomarkers

Frontage’s Bioanalytical Team is highly experienced in developing, qualifying, and validating biomarker assays. Our biomarker assay services provide accurate, reliable information. We can apply traditional and newer ELISA platforms as well as ultra-sensitive detection capabilities (Quanterix Simoa) for quantitation in the femtogram/mL range including single and multiplex analysis in various disease categories.

When biomarkers are present at extremely low levels in the early stages of physiological abnormalities (i.e. well before the onset of disease symptoms) or when they are downregulated by therapeutic intervention, detection and quantification can enable early diagnosis and prediction of therapeutic effectiveness. However, too often traditional assay platforms cannot meet the required assay sensitivity needed. The sensitivity of the Quanterix Simoa analyzer makes it the instrument of choice for ultra-sensitive analysis of biomarkers.
