Addition of a deamination modification on an N-ter cysteine | laurie josset | 2022-09-30 00:32 | |||||||||
Hello to all, I am working on the quantification of desmopressin, when I add the peptide sequence in skyline I end up with arginine vasopressin (that is normal). I tried to manually create the deamination modification to apply on the N-ter cysteine, only I don't end up with the right m/z for the precursors (I want 535.35 ++ and Skyline predicts me 545.7196 ++). For the chemical formula I indicated "O-HC", maybe this is not correct. Would it be possible to help me? Thanks in advance, Sincerely, Laurie Josset Translated with www.DeepL.com/Translator (free version) |
