These are exemplified by oligomer profiles of respiratory mucins from a cystic fibrosis patient (Lo-Guidice et al., 1994), human chorionic gonadotropin (CG) from a cell line (Hård et al., 1992), and horse chorionic gonadotropin (Hokke et al., 1994) (datasets from UniCarbKB [Campbell et al., 2014]). Here, CTSG is linked to cystic fibrosis.
