Bio-Synhthesis offers  Etheno deoxyadenosine dA (Etheno-dA) oligonucleotide modification. Ethano-dA is a highly fluorescent dA analogue with excitation maxima at 270 nm and 300 nm, and an emission meximum at 410 nm.  This modification can be incorporate at any positions within a DNA or RNA oligonucleotide for RNA structural/functional studies, protein-RNA complexes and other diagnostic applications. due to the structure of the 1, N6 etheno structure o fethno dA will not base-pair with dT or dU, for this reason, oligonucleotide modified with etheno-dA at 3' or internally does not function as sequencing or PCR primer1. Primer modified with etheno-dA must located either at or close to the 5' end.
