Antibody Product Analysis
Expert Analytical Services
in Accordance with Regulatory Guidelines Antibody products should be characterised according to ICH and FDA guidelines. M-Scan provides a full GLP/cGMP analysis package for product characterisation and identification of post translational modifications, which include: Structural characterisation and confirmation Amino acid sequence Amino acid composition N- and C- terminal sequence
N-terminal sequencing (automated Edman) MS/MS peptide sequencing
Peptide map Sulphydryl groups and disulphide bridges Carbohydrate structure
Monosaccharide composition analysis Oligosaccharide profiling by HPAEC-PAD and MS Linkage analysis Glycosylation site determination
Deamidation Oxidation Physicochemical properties Molecular weight or size
Gel electrophoresis MALDI-TOF or ES-Q-TOF-MS
Isoform pattern Extinction coefficient Electrophoretic pattern
Including CE
Liquid Chromatographic patterns
Reversed Phase Size Exclusion Ion-Exchange profiling
Spectroscopic profiles
Circular Dichroism NMR
Aggregation
Analytical Ultracentrifugation (AUC) SEC/MALLS
