| 20080248536 | Polynucleotide Ligation Reactions - The method of the invention improves the specificity of a ligation reaction carried out between a first double-stranded polynucleotide having a single-stranded portion and a second polynucleotide having a complementary single-stranded portion, the second polynucleotide being present in a sample comprising a mixture of different polynucleotides. The method comprises contacting the sample, under hybridising conditions, with the first polynucleotide and one or more third polynucleotide(s) wherein the third polynucleotide(s) comprises a single-stranded portion that differs from the single-stranded portion of the first polynucleotide by at least one base substitution. | 10-09-2008 |
| 20080261204 | Polynucleotide Ligation Reactions - The method of the invention is useful in quantifying the absolute or relative number of unique molecules present in a sample after carrying out an analysis procedure on the sample, and comprises the steps of: (i) attaching a unique molecular tag to substantially all of the molecules in the sample; (ii) carrying out the analysis procedure using the molecules of the sample; and (iii) on the basis of the molecular tags determining the absolute or relative number of unique molecules present in the original sample which underwent the analysis procedure. | 10-23-2008 |
| 20080286768 | Sequencing a Polymer Molecule - A method for sequencing a target polymer molecule comprises the steps of: (i) treating the target polymer with an agent that degrades sequentially at least one end of the target polymer; (ii) converting at least a portion of the degraded end of different degraded polymers into a readable signal sequence, and labeling each of said degraded polymers with a tag that represents the relative order of degradation; (iii) determining the sequence of the readable signal sequence; and (iv) determining the sequence of the target polymer using the sequence data obtained in step (iii) and the identification of each associated tag. | 11-20-2008 |
| 20090047744 | Method for Improving the Characterisation of a Polynucleotide Sequence - A method of identifying at least one characteristic of a target molecule comprises the steps of: (i) converting the at least one characteristic into a signal polynucleotide; and (ii) identifying the signal polynucleotide sequence, thereby identifying the at least one characteristic of the target molecule wherein each signal polynucleotide comprises at least one control sequence that defines a characteristic of the signal polynucleotide, and wherein identification of the control sequence confirms whether the signal polynucleotide sequence has been identified correctly, and, optionally, if the identification is not correct, provides the necessary information to determine what the correct signal polynucleotide sequence should be. | 02-19-2009 |

| 20090087834 | Method for characterising polynucleotides - The method of the invention is used to identify specific characteristics of a target polynucleotide in a sample, and comprises the steps of: i) attaching to one end of each target polynucleotide in the sample a polynucleotide signal sequence that is specific for the characteristic under study; ii) contacting the target polynucleotides with a molecule that interacts with the target polynucleotide if the characteristic is present; iii) attaching a polynucleotide adapter sequence to those targets polynucleotides that interact with the molecule of step (ii), the adapter being attached at the end of the target polynucleotide opposite that at which the signal sequence is attached; iv) carrying out a polynucleotide amplification reaction on those target polynucleotides that comprise both the adapter and signal sequence, optionally repeating steps (i) to (iv) for other characteristics; and (v) identifying which signal sequences are present on the amplified products, and in which order, to thereby determine the characteristics of each target polynucleotide. | 04-02-2009 |
| 20090239213 | Identifying a target polynucleotide - A method for identifying the presence of a single stranded target polynucleotide in a sample comprising the steps of (i) contacting the target polynucleotide, under hybridising conditions, with at least first and second polynucleotide probes, each of which comprise a first region complementary to adjacent non-overlappïng regions of the target polynucleotide; (ii) ligating together those first and second polynucleotides that hybridise to the target polynucleotide; (iii) optionally, amplifying any ligated polynucleotides; and (iv) determining whether the target polynucleotide is present in the original sample, by detecting any ligated polynucleotide, wherein at least one of the first and second polynucleotides comprise a second region having a defined polynucleotide sequence, with each individual nucleotide of the first region being represented by at least two nucleotides on the second region, and the ligated polynucleotide being identified by determining the second region of at least one of the first and second polynucleotide probes. | 09-24-2009 |
