摘要：An optically detectable analytical composition comprising a rare earth dopant, acarrier incorporating the rare earth dopant, and at least one of: a chemical linker suitableto bind to a biological binding agent and a biological binding agent is disclosed.

Preferred embodiments include a glass micro bead carrier treated to attach a biologicalbinding agent such as a protein, or a nucleic acid. The binding agent can bind to a targetspecies in a sample and thereafter be used to determine the presence, concentration orabsence of the target in the sample. The composition can be used in a number ofdifferent applications, such as to perform fragment analysis of DNA. The narrow bandsemitted by rare earth dopants when excited, allows for a large number of such dopantsto be incorporated into an individual carrier, allowing detailed characterisation of thesample to be conducted in a reduced number of sample test runs.
