  • Publication number: 20130273521
    Abstract: The invention concerns a system for detecting a target nucleic acid molecule of a particular sequence in a sample, said system comprising (i) an oligonucleotide primer complementary to a said target nucleic acid molecule, which primer has no internal complementarity, is able to amplify said target sequence and carries a first label linked to said oligonucleotide at its 5? end; and (ii) an oligonucleotide probe which carries a second label that is able to interact with said first label to produce a detectable signal, wherein the oligonucleotide probe binds an extension product of said primer such that the first and second label can interact to produce a detectable signal. Methods for using said system in particular in a nucleic acid assay, kits comprising the system and elements of it form a further aspect of the invention.

  • Publication number: 20120208192
    Abstract: A method for carrying out an isothermal nucleic acid amplification reaction at a predetermined temperature, said method comprising changing the temperature of the reaction mixture away from the said predetermined temperature and allowing it to return to the predetermined temperature at least once during the amplification reaction so as to cause a temperature oscillation in particular of up to 15° C., for example of from 2-10° C. Apparatus adapted to carry out the method forms a further aspect of the invention.

  • Publication number: 20120003726
    Abstract: Biochemical assay apparatus uses a container with a sleeve of electrically-conductive material (300) to heat it. The heating is done inside a chamber and a contactless heat sensor (110) such as a thermopile or a bolometer, also inside the chamber, is used to monitor the temperature of the electrically conductive material (300). There are many factors that distort the output of the heat sensor (110), particularly as the temperature rises and properties such as emissivity change, or as time goes by and tarnishing and dust affect the heat sensor output. Because the sleeve has low thermal mass and heat transfer only has to happen over short distances, it is relatively easy to calculate a change in actual temperature of the electrically conductive material (300) when subjected to a known pulse of drive current and this property can be used to calibrate the performance of the heat sensor (110) in situ in the chamber.

  • Publication number: 20110045485
    Abstract: RNA-containing probes and kits comprising RNA-containing probes for the detection and analysis of nucleic acid sequences are described. These probes are contacted with a sample suspected of containing the nucleic acid sequence and if they form duplexes, they are hydrolysed. This may be done, for example during an amplification reaction. AMP generated as a result of the hydrolysis is converted to ATP. The ATP may then be detected using bioluminescent reagents. Inclusion of modified adenosine in at least one probe means that the signal arising from one probe will give rise to a different and distinguishable bioluminescent signal thus enabling the use of for example an internal control in bioluminescently-reported nucleic acid tests.
