Characterization of a pharmaceutical or biological entity includes analysis of its structure, activity, stability, potency and behavior in a formulation. A well-characterized drug product reduces the risk of unknowns. For example, any process impurities, intermediates or excipients which might affect the product’s potency could go undetected in the absence of a complete characterization program.

Bioanalytical Laboratory Testing at Pacific BioLabs

The analytical and bioanalytical laboratory at Pacific BioLabs has over 20 years of experience in developing and validating methods for characterization of pharmaceuticals, biologics and conjugates to support initial lead candidate selection through downstream manufacturing. With its team of chemists and scientists and state-of-the-art instrumentation, our bioanalytical laboratory has performed characterized well over 400 small molecules and biologics.

Notably, our team has characterized a whole spectrum of biological products including enzymes, carbohydrates, peptides, antibodies, PEGylated proteins, vaccines, and antibody-drug conjugates.
