(a) Molecular mass distributions of proteins identified using top-down and bottom-up analysis. Theoretical molecular masses were calculated using amino acid sequence. (b) Overlap of proteins identified using top-down and bottom-up analysis (considering proteins identified by at least two unique peptides).
