Biomarkers & Precision Medicine

Frontage can provide you with unmatched experience in biomarker assay development, validation, and sample analysis.

As your biomarker analysis partner, you can be assured of getting the optimal solution to address your needs at any part of your biomarker journey, for everything from custom and exploratory to regulated studies.

Frontage’s biomarker team is highly experienced in developing, qualifying, and validating biomarker assays.

We work in consultation with customers to develop a tiered approach to validation depending on the needs of the program or phase of development of the biomarker.

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. 

Assay Feature: pTau217

Frontage launches a new ultrasensitive assay for the quantitative determination of pTau217 in various sample types. The plasma phospho-Tau (pTau) species have emerged as the most promising blood-based biomarkers of Alzheimer’s disease.

Broad Range of Capabilities and Experience in Biomarker Assay Services 

Our biomarker scientists have developed and validated many biomarker assays for pharmaceutical and biotech companies. We are proud to become a benchmark in the field and have a significant impact on our clients using our expertise and state-of-the-art technology to advance/monitor drug development. We have also published novel biomarker assays developed in-house to share our expertise with the industry. With the addition of new technologies such as O-link and SMCxPRO for biomarker analysis, we believe we will continue as a top-notch provider of biomarker assay services in the years to come.
