AMPLIFICATION OF SIGNAL USING A BEAD-BASED OLIGONUCLEOTIDE ASSAY

The present invention regards amplification of a signal from a hybridization-based oligonucleotide assay. In some embodiments, a bead comprises an oligonucleotide hybridized to a labeled polynucleotide from a sample, and a signal generated from a complex thereof is amplified through labeled antibodi...

Summary:The present invention regards amplification of a signal from a hybridization-based oligonucleotide assay. In some embodiments, a bead comprises an oligonucleotide hybridized to a labeled polynucleotide from a sample, and a signal generated from a complex thereof is amplified through labeled antibodies directed to a receptor for the label. In particular embodiments, the assay provides information on gene expression. La présente invention concerne l'amplification d'un signal à partir d'un dosage oligonucléotidique à hybridation. Dans certains modes de réalisation, une bille comprend un oligonucléotide hybridé avec un polynucléotide marqué d'un échantillon, et un signal généré à partir du complexe obtenu est amplifié à l'aide d'anticorps marqués dirigés vers un récepteur de la marque. Dans des modes de réalisation particuliers, le dosage fournit des informations sur l'expression génique.
