Identification of transthyretin peptides upon plasmin digestion by N-terminal sequencing. Band 1 starts at the amino acid residue 49, whereas band 2 starts at the first amino acid residue in the transthyretin polypeptide chain, indicating that band 1 corresponds to the 49–127 C-terminal fragment and band 2 to the 1–48 N-terminal fragment.
