A significant amount of information about
a protein can be determined using peptide
mapping. However, additional information
can also be found through characterization
of the whole protein (or light and heavy chain
fragments). Accurate mass and, to some
degree, the heterogeneity of the protein
can be determined. Intact mass is also an
important step after manufacture, to ensure
the stability of the biotherapeutic drug after
storage. Intact mass characterization is
sometimes referred to as “top down” for
the proteins and is challenging compared to
peptide mapping, due to the large mass and
complex nature of the samples.
