(a), (b) The nucleotide composition analysis showing compositional differences in A, G, T and C (dA, dG, dT and dC) resulting from insertion, deletion or substitution or by combination as observed in erroneous sequence reads, respectively, from Run 1 and 2 of antibody #1. Compositional differences are denoted by numeric values with "+" sign for overrepresentation and "-" sign for underrepresentation at the vertical axis and the total number of recurring erroneous reads in percent at the horizontal axis.
