Bio-Syntehssi offer ATTO 390 fluorescent dye oligonucletoide labeling services. ATTO 390 label with a coumarine structure. This dye have high quantum yield, large stoke-shift with good photo-stability. Its fluorescence can be excited in range of 360-410 nm. Thsi compound requirea primary amine for conjugation onto an oligonucleotide via NHS ester conjugation chemistry. Click reaction is also available. Dual HPLC purification is used to remove failure sequences during first HPLC purification,  after labeling, the second HPLC is performed to remove unlabeled oligonucleotides and excessive dye in order to obtain a full length labeled oligonucleotide.
