Atto 565 is a new label with high molecular absorption (120.000) and quantum yield (0.9) as well as sufficient stoke′s shift (excitation maximum 563 nm, emission maximum 592 nm). It does nearly not show cis trans-isomerisation, which limits brightness and reproducibility for many other dyes. Due to an insignificant triplet formation rate it is well suited for single molecule detection applications. Streptavidin conjugation of Atto 565 does not significantly change the labels spectral data regarding excitation and emission maxima. Atto 565-Streptavidin is used to label biotin conjugated molecules.
