Modifying DNA During Synthesis
Modifying DNA during synthesis involves a bit of creativity along with untraditional chemistry throughout the synthesis workflow. Different classes of modifiers have grown over time, but the most tried and true begins with 3’ or 5’ amino modifiers and the use of spacers and “branching” modifications. This paved the way for introducing more elaborate modifiers into sequences, such as compounded functional groups and a wide array of labels.
