Peptide synthesis and purification
The core facility offers peptide synthesis as a service employing the so-called "solid-phase peptide synthesis (SPPS)1". Standard Fmoc chemistry is primarily used for the preparation of peptides and mini-proteins containing proteinogenic, modified-proteinogenic and non-proteinogenic amino acids.
The synthesis services cover both manual and automated techniques. For the automated synthesis, the following devices are employed:
Economy Peptide Synthesizer EPS 221 (Intavis) & ResPep SL (Intavis)

Purification of the raw peptides is achieved by preparative HPLC (example):
verschiedene Säulen (C4, C8, C18, 250 x 30 mm, 250 x 22 mm, 250 x 4,6 mm) SL (Intavis)

Different amounts ranging from 1-200 mg can be applied.
Requests involving complex synthesis procedures such as controlled closure of disulfide connectivities, postsynthetic modifications of amino acids/peptides, native chemical ligation and others can be performed after individual consultation2.
