Bio-Synthesis offers ATTO 520 fluorescent dye oligonucleotide labeling services. ATTO 520 is related to Rhodamine 6G. Characteristic features of the label are strong absorption, high fluorescence quantum yield, and high thermal and photo-stability. The fluorescence of ATTO 520 is excited most efficiently in the range 510-535 nm, A suitable source of excitation is an Argon-Ion laser using the 514 nm line. They dye can be use as an alternative dye for JOE, TET dye. Features:
