|precursor isotopic envelope||bobxiong||2022-08-31|
Hi Skyline Team,
In Skyline Proteomics interface, theoretical isotopic precursors with m/z values lower than the monoisotopic precursor were displayed. My understanding is that the monoisotopic species is of the lowest m/z (I could be wrong though as I am not familiar with the various ways of determining the isotopic envelope). I attached a screenshot here. The Skyline zip file was uploaded to https://skyline.ms/files.url (file name monomer.sky.zip).
I was trying to understand this to help interpret a related Skyline analysis in Molecule interface.
Thanks a lot,
Bob Xiong, Ph.D.
