Abstract
Particles loaded with lanthanide (III) rare earth metal ions chelates for use as labels in binding assays. Particles and uses for detecting analytes in samples is described.
Claims22
A particulate reagent comprising:
- a first particle having a lanthanide chelate complex loaded into the first particle, and
- a first binding partner for an analyte coated on the first particle, wherein
- (a) the first binding partner is directly coated on the first particle covalently or non-covalently, or
- (b) the first particle is directly coated covalently or non-covalently with streptavidin or neutravidin, and the first binding partner is bound to or becomes bound to the first particle through biotin/streptavidin or biotin/neutravidin interaction.
