With very few exceptions, our peptides are synthesized by chemical methods.

The source (synthetic/recombinant) is explicitly mentioned in the product entry and included in the designation of recombinant peptides (rec).

Bachem’s peptides are obtained either by “classical” solution-phase synthesis or by solid-phase synthesis (SPPS). The peptide is elongated starting from the C-terminus to the N-terminus of the sequence.
