Abstract Information :
Antibody drugs are expected to enhance the effect of therapies without adverse side effects. During the manufacturing processes of immunoglobulin G (IgG), which is a main ingredient of antibody drugs, aggregates and fragments can be formed which may react as impurities. Size exclusion chromatography (SEC) analysis is a common method for determination of IgG characteristics as well as quality control in the production processes of IgG. YMC has developed a new SEC column with 2 µm particle size and with a Diol bonded phase, YMC-Pack Diol UHPLC.
High resolution analysis of aggregates and derived fragments can be performed with this new SEC column. Furthermore, smooth method transfer from conventional 5 ?m SEC column to this new SEC column can also be achieved while reducing analysis time by using a shorter column. In this poster, we introduce the advantages of this 2 µm YMC-Pack Diol SEC column through several examples of IgG aggregates and fragments analysis.
