BIOshell columns from Merck Supelco consist of core-shell particles for bioseparations ranging from glycans to large proteins. These columns are compatible with HPLC and UHPLC systems as well as for MS detection.
BIOshell IgG 1000 Å: for mAbs, ADCs, biosimilars, H/D exchange, mAb fragments
BIOshell A400 Protein: mAbs, ADCs, biosimolars, Proteins, mAb fragments
BIOshell A160 Peptide: for tryptic digest, post-translational modifications, polypeptides
BIOshell Glycan: for oligosaccharides via HILIC

Measurement of denosumab with different columns.
Monoclonal antibodies are unique molecules and therefore can interact differently with different phase chemistries.
The numbered peaks correspond to IgG2 disulfide bond variants.
