Abstract
A mixture of microscopic particles, each bearing a given allele-specific oligonucleotide probe and a reporter group defining the particle category, enables simultaneous detection of several gene mutations, providing that each particle may be separately subjected to measurement. It has been shown(1) that a highly sensitive miniaturized assay format may be developed by using uniformly sized (50 mu m) polymethacrylate particles as a solid phase, and a photoluminescent europium chelate for detection. We now report on alternative ways of tethering the oligonucleotide probe to the microparticles, and discuss the effects of various linkers on the hybridization properties.
