Bioanalytical Strategies for Insulin Analogues & Other Large Peptides Using LC-MS

Learn from Michael Blackburn, Head of Bioanalytical Method Development and Labs, how our physiochemical-based approach enables us to accelerate the development of bioanalytical assays for insulin analogues.

Insulin analogues, along with other large peptides, such as GLP-1 receptor agonists, represent a major and growing class of biotherapeutics. Their quantification plays an important part in improving the outcome of downstream formulation development and clinical study activities. However, there are sensitivity challenges when trying to measure trace levels of these types of compounds which require advanced technologies such as LC-MS.

Presentation Overview

In this presentation, Michael Blackburn, Head of Method Development and Labs, will describe the bioanalytical strategy that Quotient Sciences employs to best support clinical trials for these compounds and how our physiochemical-based approach enables us to accelerate the development of bioanalytical assays for insulin analogues.

Through case studies, our speaker will touch on some of the pitfalls and solutions that our team of experts have encountered in this field and share what scientists should be aware of when interpreting how LC-MS data correlates with immunoassay data. Using assay validation data, we will cover high-throughput sample analysis and the potential impact of anti-drug antibody effects.
