Abstract: Disclosed is a system and method conducting real-time PCR. Capture molecules of a specific design are immobilized on a solid support, and contacted with amplicons produced in one or more PCR cycles. Detection of amplicons may take place during or between the PCR cycles while the solid support is in fluidic contact with the PCR solution. In an alternate embodiment detection of the amplicons takes place when the solid support is not in fluidic contact with the PCR solution. The method is suitable for the simultaneous detection and quantification of closely homologous target molecules.

Abstract: A method for identifying or quantifying an organism by a detecting its nucleotide sequence among at least 4 other homologous sequences comprising amplifying nucleic acids from the organism to generate target nucleotide sequences to be detected; contacting the target nucleotide sequences with single stranded capture nucleotide sequences bound by a single predetermined link to an insoluble solid support and discriminating the binding of a target nucleotide sequence specific of an organism with a signal resulting from a hybridization by complementary base pairing between the target nucleotide sequence and its corresponding capture nucleotide sequence is disclosed. The capture nucleotide sequence is bound to the insoluble solid support at a specific location on an array having a density of at least 4 different bound single stranded capture nucleotide sequences/cm2.

Abstract: Disclosed is a system and method conducting real-time PCR. Unlabeled capture molecules of a specific design are immobilized on a solid support, and contacted with amplicons produced in one or more PCR cycles. Detection of amplicons may take place during or between the PCR cycles while the solid support is in fluidic contact with the PCR solution. In an alternate embodiment detection of the amplicons takes place when the solid support is not in fluidic contact with the PCR solution. The method is suitable for the simultaneous detection and quantification of closely homologous target molecules.
