| abstract |
The invention relates to new fluorescent dyes from the class of cyanine dyes, in particular indotricarbocyanines, with an absorption and fluorescence maximum in the spectral range from 700 to 900 nm, with a reaction group specific for the thiol group and three, preferably four, sulfonate groups, to increase the solubility in water, as well as obtaining dyes. The present invention also relates to conjugates of these dyes with biomolecules and their use. |
