Schematic representation of the designed reference material (RM). Grey bars indicate the assay sequences represented in the RM. The red lines and letters (red: WT, grey: MUT) schematically indicate the single nucleotide mutation-sites in the RM sequence which are represented as multiple “MUT”-labeled peaks in the MassARRAY® spectrum.
