Unmodified peptides

Unmodified peptides


We provide routine synthesis of peptides from 6-30 amino acids. These peptides can be ordered online. Peptides that are longer than 30 amino acids are first analysed for feasibility prior to acceptance. We recommend that highly hydrophobic peptides be optimized, when possible, by reducing the number of hydrophobic residues. This will not only increase synthesis quality, but also play an important role in your biological applications.


Peptides are available as crude, > 70 %, > 85 %, > 90 % and > 95 % purity depending on your research applications.
  • SePop purified peptides (average purity 60 %): useful for screening purposes
  • Immunograde peptides (> 70 % purity): useful for generating or testing antibodies. Since the presence of organic impurities inherent to the synthesis process can induce side effects during the antibody production procedure, like inflammation or toxicity, a special treatment for the complete extraction of organic impurities is applied, and where necessary, a standard purification step is also added.
  • Biochemistry grade peptides (> 85 % purity): semi-quantitative work
  • High purity peptides (> 90 % and > 95 % purity): for quantitative results
Peptides with purities higher than 85% are adequate for enzymology or biological activity studies. They are checked by HPLC using a photodiode array detector and by Mass Spectrometry. These quality data are included with the peptide delivery.
