Development of an affinity HPLC analytical method for the quantification of IgM with monolithic columns
Extensive research in the last two decades has led to the realization of Immunoglobulin M (IgM) as a potential therapeutic and diagnostic agent for autoimmune diseases, infectious diseases and as an AIDS and cancer vaccine. Growing interest in these molecules has created a need for an accurate, rapid and simple analytical method to measure IgM concentrations during the production (in-process control) in cell culture supernatants as well as in all purification steps in the downstream processing.
Convective interaction media (CIM) monolithic columns has been increasingly recognized as a quantification tool for large molecules. Affinity ligands like protein A and protein G are the most common ligands used for antibody capture and analysis.
