The peptide ligation chemistry in addition to solid-phase peptide synthesis is used to synthesize relatively longer peptide molecules with typical length of 125 residues (Boerema, 2007). The ligation methods overcome the length limitation of solid-phase synthesis, because the chemical ligation involves the joining of mutually reactive peptide segments created by solid-phase synthesis. The peptide bond in ligation is formed between an unprotected peptide and a peptide-thioester (Boerema, 2007). The shorter peptide segments are more rapidly prepared and are less susceptible to solubility issues in longer peptide chains.
