Biopharmaceutical Characterization Techniques for Early Phase Development of Proteins

Characterization of biopharmaceuticals (proteins) during early development is done for several reasons. The most important reason is the need to have supporting data that demonstrates the comparability of material used throughout development. This is particularly important as the production process is optimized and small changes in the process may affect the structure of the product. Demonstration of comparability of proteins produced throughout product development is more complicated, due to the inherently heterogeneous nature of many biologicals.
