    Abstract: Methods are provided for reducing background signals encountered in nucleic acid hybridization assays and other assays that involve hybridization of a labeled oligomer to its complement. The method is premised on the significant reduction of signal generation that occurs when a quenchable dye-labeled oligomer forms a hybrid complex. In addition, a method is provided for enhancing the detectable signal emitted from an amplification multimer hybridized to an oligomer probe to which a quenchable dye has been conjugated through a linker such that the emission from the dye is not quenched upon hybrid complex formation. Novel oligonucleotide probes are also provided that comprise an oligomer to which has been directly or indirectly through a linker a quenchable dye.

    Abstract: A luminometer comprising a tray for receiving an array of sample wells, a photodetector assembly, and device for relatively moving the tray and photodetector assembly in one direction to align the sample wells received by the tray in a predetermined sequence with the photodetector assembly. The photodetector assembly of the luminometer includes a stage, a photodetection head having a detection aperture permitting passage of light therethrough, a device for mounting the photodetection head to the stage that permits movement of the head in a direction substantially normal to the direction of relative tray and photodetector assembly movement, and a device for biasing the photodetection head toward a selected sample well so that the detection aperture is substantially isolated from light emitted from adjacent wells. Internal and external photodetector calibration systems and a sample heater are also contemplated.

    Abstract: The present invention provides primers and probes to be used in a method of enhancing hybridization of a probe to a target nucleotide sequence when the target sequence is capable of forming intramolecular secondary structures that interfere with hybridization of the probe to the target sequence. In particular, the invention includes a primer for amplifying a target nucleotide sequence, wherein at least a portion of the target nucleotide sequence can form an intramolecular secondary structure. The primer of the invention includes a primer nucleotide sequence complementary to a portion of the target nucleotide sequence that does not form a secondary structure, and a blocking sequence substantially complementary to at least a portion of the secondary structure-forming region of the amplified target nucleotide sequence, wherein the blocking sequence hybridizes to a portion of the secondary structure-forming region of the amplified target nucleotide sequence and blocks the formation of the secondary structure.
