Ascentis Express Peptide ES-C18 columns are specifically engineered to separate higher molecular weight compounds such as peptides and small proteins. These columns contain advanced Fused-Core particles that have larger pores (160 Å versus 90 Å in standard Ascentis Express), bonded with sterically-protected C18 ligands to provide extra stability (ES) at very low pH (< 1) and high temperatures (up to 100ºC). This greatly expands the application range for Ascentis Express columns.
