Claim:
1. A water soluble conjugate that comprises: (i) one or more labels; (ii) two to four moieties of peroxidase substrate, each of which is capable of serving as substrate of an enzyme with peroxidase activity and each is a residue of the following formula: wherein the labels (i) and moieties of peroxidase substrate (ii) are not the same chemical substances; wherein the labels (i) and moieties of peroxidase substrate (ii) are linked together via a linker, wherein said linker is a compound consisting of a linear chain of at least 30 consecutively connected atoms and two branching points, the first branching point at one end of the linear chain connecting the linear chain to the first of the one or more labels, and the second branching point at the other end of the linear chain connecting the linear chain to the first moiety of the two to four moieties of peroxidase substrate; wherein each of the moieties of peroxidase substrate JO is connected to the linker group via R6; wherein the first label of the one or more labels (i) is separated from the moieties of peroxidase substrate (ii) by the linker; and wherein the moieties are consecutively connected to each other by spacers such that any two moieties of peroxidase substrate are separated from each other by 5 to 30 consecutively connected atoms.
