摘　　要：A kind of protein complexes of cytochrome C with L-Arg was observed. Using L-Arg a strategy for probing the structural information of cytochrome C and protein complexes was established. At low pH solution multiply L-Arg adducts were produced and the number of binding ligand was depended on the charge state. While in neutral solution only these complexes binding with single L-Arg ligand were produced.
