Abstract

Monoclonal antibody therapy is used for many diseases such as rheumatoid arthritis, multiple sclerosis and different types of cancers. The antibodies (or mAb) specifically bind to target cells or proteins, which then stimulate the patient's immune system to attack those cells. It is possible to create a mAb specific to almost any extracellular/ cell surface target. There is a large amount of research undergone for the development of therapeutic monoclonal antibodies. Like all other protein therapeutics, mAb can undergo structural modifications derived from oxidation, deamidation, aggregation or amino acid substitution etc during production, storage and transportation. Therapeutic monoclonal antibodies (mABs) are characterized by a variety of assays to warrant drug safety and efficacy. In this study we demonstrate several tools for QA/QC of monoclonal antibody (IgG1) using Bio-chromatography. RP HPLC for peptide mapping and disulfide linkage analysis, Size exclusion chromatography (SEC) for purity and aggregation analysis and Ion exchange chromatography (IEX) to detect charge state variant due to truncation, deamidation oxidation and glycosylation. Simple and reproducible methods suitable for the QA/QC analysis of therapeutic biologics will be discussed in this presentation.
