Abstract
There is disclosed a compound of formula (I) wherein each of X1 and X2 are independently NH-A-NR1R2, and wherein A is A C2-8 alkylene and R1 and R2 are independently selected from hydrogen, C1-4 alkyl, C2-4 hydroxy-alkyl and C2-4 aminoalkyl, or R1 and R2 together form a C2-6 alkylene group which with the nitrogen atom to which R1 and R2 are attached forms a heterocyclic ring, or an N-oxide derivative thereof, and wherein the compound (I) or its N-oxide derivative is optionally in the form of an acid salt derived from an organic or inorganic acid. Also disclosed is a method of its production and its uses, including its use in analyzing a cell or biological material and detecting the emitted fluorescence signal.
