Peptide purity levels and Applications

Peptides are available as crude, > 70 %, > 85 % 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 (> 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.
