Early Protein Expression Assessment and the Value of Starting in a Proven System

In this article our experts discuss the role of early protein expression assessment as a critical technical evaluation tool in early biologics development. It highlights the importance of using commercially relevant CHO-based expression platforms like the GS® Gene Expression System to generate predictive data on molecular behavior, product quality, and manufacturing suitability. The article also explores how expression findings, when combined with developability and immunosafety assessments, support informed candidate progression decisions and reduce technical risk throughout development.
