ATTO Thio12 is a new label closely related to the well-known rhodamines. The characteristic feature of the label is high yield of triplet formation. The dye is moderately hydrophilic. After coupling to a substrate the label carries a net electrical charge of +1. In solution its fluorescence can be excited efficiently in the range 560 - 590 nm.
