Reading this result
Purity here is reported by HPLC as area percent of UV-absorbing material — the main peak’s share of what the detector saw, not a mass fraction. The quantity result is reported separately because a vial can show and still contain counterion, bound water and residual salt alongside the peptide.
DSIP is a nonapeptide first isolated from rabbit cerebral venous blood, studied for its role in sleep-related signalling. All material is supplied strictly for laboratory research use and must not be administered to humans or animals.
