Applications & Solutions


Frontage’s Bioanalytical Team is highly experienced in developing, qualifying and validating Biomarker assays. 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.

Board Range of Capabilities and Experience

Our biomarker scientists have developed and validated a large number of biomarker assays for pharmaceutical and biotech companies. We are proud to become a benchmark in the field and have a significant impact for 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 ELLA and Luminex for biomarker analysis, we believe we will continue as a top-notch provider of biomarker assays in the years to come.
