Liquid Chromatographic Pattern

Protein aggregation and degradation products as well as heterogeneity in charge variants are fundamental characteristics implicated in the stability, biological activity and immunogenicity of the therapeutic monoclonal antibody. These characteristics can be indicative of the nature of the clonal cell line, the manufacturing process or the stability of the drug, and as such can be used throughout the biological development cycle.

Size Exclusion Chromatography

BioOutsource can offer low dispersion, high resolution chromatographic methods to identify high and low molecular weight variants of your monoclonal antibody product, while also evaluating the consequence on binding and functional activity. This methodology also provides information on chromatographic patterns as required by ICH Q6b providing information on identity, homogeneity and purity.

Ion Exchange Chromatography

BioOutsource also offer Ion Exchange Chromatography (IEX). You can find more information on this method on our charge variant page.

A comparative approach can also be implemented for developers of biosimilar mAb therapeutics. We run side by side analysis of the biosimilar material to a reference material. This can highlight examples whereby issues may arise in proving fingerprint-like similarity.
