Separation of the IgG-hexamer samples. (A) Samples of NC (a, b), CLL patients (c–f) and commercial IgG (g, h) were separated and silver stained. Heavy (γ) and light chain are indicated by arrows. Additional proteins besides heavy and light chains are marked in frames. (B) The process of selection of the resulting sequence data included elimination of all the IgG-related sequences, low molecular mass peptides, sequences with a total number of identified peptide sequences (peptide spectrum matches-#PSMs)<30, and sequences with coverage<25.
