Three structural features are relevant to solution preparation, chromatography and mass spectrometry in the laboratory.
39-Residue Backbone
A linear synthetic sequence of 39 amino acids prepared by solid-phase synthesis. Resolved as a single principal peak by reversed-phase HPLC.
Non-Natural Residues
Incorporates Aib and a fluorinated aromatic residue. Non-natural residues alter fragmentation patterns in MS/MS and serve as identity markers during characterization.
C20 Fatty Diacid Side Chain
A long-chain diacid attached through a linker to a lysine side chain. The lipid group increases hydrophobicity, which appears as a longer reversed-phase retention time and a tendency to self-associate at high concentration. Select gradient and ionization conditions accordingly.
Every lot is tested by an independent third-party laboratory. The tests below correspond to the results reported on the Certificate of Analysis linked on this page. Refer to the certificate for the values for the specific lot.
Purity (HPLC)
Reversed-phase HPLC with UV detection. Specification ≥99% by peak area.
Net Content
Peptide content per vial determined by HPLC peak area against the labeled quantity. Specification 90–115% of label claim.
Appearance
Visual inspection of the lyophilized material against the specification of a white lyophilized powder.
Certificate Verification
Each certificate carries a verification code that can be checked directly on the issuing laboratory’s website.
Storage Conditions
Lyophilized (powder): -20°C, protected from light and moisture. Stable for 24+ months under recommended conditions.
Handling: allow the sealed vial to reach room temperature before opening to avoid condensation. Prepared laboratory solutions should be protected from light and used promptly; avoid repeated freeze-thaw cycles.
