Abstract: Polynucleotides are provided which are useful as amplification primers and hybridization probes for detecting BS106 target sequence in a test sample. The primers and probes can be employed in amplification based methods for detecting the presence of BS106 sequences in a test sample. Additionally, the primers and probes can be used to perform homogeneous, real time reverse-transcriptase polymerase chain reaction to detect BS106 target sequence in a test sample.

Abstract: Methods, devices, apparatus and kits for amplifying and detecting nucleic acid are provided. The apparatus is a one or two-tier thermal cycling device that operates in conjunction with a reaction/detection unit. A sample is loaded into a reaction chamber of the device which is then mated with a detection chamber to form the reaction/detection unit. A first heating element of the thermal cycling apparatus applies a desired temperature to the reaction/detection device to amplify target nucleic acid in the sample. The reaction mixture is then transferred to the detection chamber by the second heating element and amplified target nucleic acid is immobilized on a support in the detection chamber. Microprocessor control controls the heat applied by the second element independently of the heat applied by the first element. A detection system associated with the apparatus detects and analyzes the immobilized amplified nucleic acid target.

Abstract: Provided herein are methods for detecting multiple target nucleic acid sequences in a test sample. Also provided is a hybridization platform useful for detecting multiple target sequences in a test sample. The hybridization platform comprises a solid support material having a defined pattern of capture probes immobilized thereon.

Abstract: The present invention provides a method of detecting the amount of a target sequence which may be present in a test sample. The method uses an aggregate primer series, which comprises at least two primer sets, in an amplification reaction to detect the relative concentration of a target sequence which may be present in a test sample. The primer sets have different sensitivities and hybridize with sub-target sequences which are different regions of the target sequence. The method generally comprises cycling a test sample suspected of containing a target sequence, an aggregate primer series, and means necessary for performing an amplification reaction; and detecting any amplified sub-target sequences. Based on a qualitative detection of the amplified sub-target sequences generated by individual primer sets, the relative quantity of the target sequence can be determined.

Abstract: Methods, devices, apparatus and kits for amplifying and detecting nucleic acid are provided. The apparatus is a thermal cycling device that operates in conjunction with a reaction/detection unit. A sample is loaded into a reaction chamber of the device which is then sealably mated with a detection chamber to form a sealed reaction/detection unit that is virtually irreversibly closed. One or more heating elements of the thermal cycling apparatus applies a desired temperature to the reaction/detection device to amplify target nucleic acid in the sample. The reaction mixture is then transferred to the detection chamber and amplified target nucleic acid is immobilized on a support in the detection chamber. A detection system associated with the apparatus detects and analyzes the immobilized amplified nucleic acid target. Kits include the reaction/detection units and reagents for amplification.

Abstract: An improved, "gap filling" embodiment of the Ligase Chain Reaction (LCR) is described. Gap filling LCR is LCR wherein at least one of the probes is recessed so that a gap is formed between the adjacent probes when they are hybridized to target. The gap is filled using polymerase and deoxyribonucleotide triphosphates before ligation of the probes together. There are single and double gap versions, depending on whether one or two probes are recessed and require filling before ligation. The improvement resides in selecting and using target sequences such that only a single type, or two types, of deoxyribonucleotide triphosphate(s) are required to fill double gaps each being 1-10 bases in length, preferably 1-3 bases. Probes having specific sequences are claimed for a number of pathogens.
