MALDI-TOF mass spectrum of P4LC (m/z: 2315.5) obtained after purification indicates a 3:1 LVFX/Pep-4 loading stochiometry. No peaks assignable to Pep-4 or intermediately acylated conjugate species were observed. The baseline isotopic distribution for P4LC is shown in the inset with labeling of the monoisotopic peak.
