Fluorescent labels having a polysaccharide bound to polymeric particles
First Claim
1. A fluorescent label comprising a polysaccharide bound to a polymeric particle which is derived from a loadable latex having a discontinuous phase which consists essentially of a polymer prepared from one or more ethylenically unsaturated polymerizable monomers, and an aqueous phase, said polymeric partilce having incorporated therein a fluorescent rare earth chelate.

Abstract
Fluorescent labels comprise a polysaccharide bound to a polymeric particle which contains a fluorescent rare earth chelate. These labels can be attached to any of a variety of physiologically reactive species to provide labeled species which have improved stability in aqueous solutions. The labeled species are particularly useful in specific binding assays to determine an immunologically reactive ligand, e.g. a hapten, in either solution or dry analytical techniques.
