Abstract
The present invention relates to processes for the production of peptides, and the peptides produced accordingly. Peptides produced according to the invention may be produced more efficiently than peptides produced according to prior art processes. The production process of the invention may lead to advantages in yield, purity, and/or price. Methods of marketing peptides are also disclosed.

A method for producing a target peptide, the method comprising:
- expressing a heterologous fusion peptide in a genetically modified cell, the heterologous fusion peptide comprising an affinity tag, a cleavable tag, and the target peptide, wherein the cleavable tag is tryptophan (Trp), and wherein the affinity tag or the cleavable tag is heterologous to the target peptide;
- binding the heterologous fusion peptide to an affinity material via the affinity tag;
- and
- cleaving the heterologous fusion peptide with DMSO while bound to the affinity material to release the target peptide, thereby producing the target peptide.
