Peptides and Proteins

This spectrum shows the signal from a four-fold charged peptide A of mass 3853.87 amu.

The mass resolution is 20000 (FWHM)


This is a complete spectrum of peptide B.
It shows the 3-, 4-, and 5-fold
charged monomer, and the 7-, 8-, and 9-fold charged dimer of this peptide.


This spectrum shows the 4-fold charged monomer of peptide B above the 8-fold
charged dimer.


This spectrum shows the alpha- and beta- chain of hemoglobin (bovine),
the insert shows the isotopic distribution of the 13+ charge state.
