Analytical Methods

HPLC-UV/MS

Purity, Potency & Identification

All chemical analysis was performed by HPLC with UV detection coupled with mass spectrometry. Chromatographic purity is determined by area normalization. Net peptide content is quantified against label claim. Identity is confirmed by mass spectrum — observed ions [M+H]+ at 341.05 m/z and [M+2H]2+ at 171.00 m/z.
