ABSTRACT:
A fluorescent labelling composition comprises a linear polysaccharide backbone molecule having a plurality of target-binding molecules, such as antibodies or nucleic acids, attached at spaced-apart intervals thereon. Each of the target-binding molecules, in turn, includes a multiplicity of fluorescent dye molecules bound thereto. In this way, fluorescent signal introduced to a single target-site on a solid phase surface may be increased without loss of binding activity.
