To date, a systems-level investigation evaluating the epigenetic states of cell systems on the resulting glycome has not been

• molecules were dyes used for the DNA/RNA labelling or even monitoring or influencing DNA/RNA function [3][4]. However, due to the complexity of DNA-coded or RNA-coded processes, also including epigenetics, there is permanent need for novel dyes, differing in selectivity, colour, or method of monitoring [5
