Our peptides are purified by Reversed Phase HPLC (RP-HPLC). HPLC purification permits the removal of deletion and truncated sequences, scavengers, and TFA (Trifluoroacetic Acid) used to deprotect and cleave the peptide from the resin, which could otherwise be extremely toxic and interfere with the expected activity of the peptide.
We offer three different degrees of purity:
- Crude peptides for generation of peptide libraries and for preliminary experimental screening
- 70% for immunological purposes
- 95% for biological activity studies in vitro, animal studies, and for biochemical reactions, such as binding experiments or receptor studies.
