Biophysical Characterization

Many of our biophysical characterization methodologies examine a product's higher-order structure (HOS), which may include secondary and tertiary structure, aggregation and oligomerization. Correct HOS configuration is critical to ensure proper functionality, activity and stability of a biopharmaceutical product. Secondary and HOS characterization capabilities are essential for a complete product characterization program.

Upcoming Seminar

Three of our scientists discuss the analytical methods used to characterize gene therapies including delivery vectors such as rAAVs and lentiviruses.
