This product is for Research use only. In case of intended commercialization, please contact the IP-holder (ATTO-TEC GmbH, Germany) for licensing.


Atto 590 is a new label with high molecular absorption (120.000) and quantum yield (0.80) as well as sufficient stoke′s shift (excitation maximum 594 nm, emission maximum 624 nm). Due to an insignificant triplet formation rate it is well suited for single molecule detection applications. Biotin conjugates can be used in applications like ELISA or immunohistochemistry, in situ hybridization, flow cytometry and others, to identify streptavidin, avidin, or extravidin-conjugates.
