Abstract
A luminescent cyanine dye having generally the following structure ##STR1## wherein the dotted lines represent one to three rings having 5 to 6 atoms in each ring. R.sub.3, R.sub.4, R.sub.8 and R.sub.9 groups are attached to the rings. At least one of the R.sub.8 and R.sub.9 groups is a sulfonic acid or sulfonate group and at least one of the R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.7 groups is a reactive moiety that reacts with amino, hydroxy or sulfhydryl nucleophiles.
