Recombinant therapeutic antibodies have shown a great potential in the treatment of several severe medical conditions such as cancer and autoimmune diseases. Glycosylation plays a critical role in biological activity and immunogenic properties of these compounds. The analysis of glycan profiles is therefore necessary in many steps of the development and manufacturing process from early development to quality control of the final product. In this paper, a fast, parallel, and robust sample preparation platform for glycosylation profiling using a microfluidic compact disc (CD) is presented. A sequential process including selective capture of antibody from a crude cell supernatant using protein A beads, enzymatic release of glycans, purification with a graphitized carbon black column, and crystallisation for MALDI-TOF analysis were performed on the CD. Glycosylation profiles of an antibody intended for therapeutic use produced in two different cell lines were compared.
