摘要:
A method for efficiently constructing a cDNA library having a reduced content of cDNA clones derived from a highly expressed gene is provided. According to the method for constructing a cDNA library using a double-stranded DNA primer having oligo dT and mRNA as a template, the proportion of cDNA clones derived from a highly expressed gene in a cDNA library was decreased through coexistence with a probe having a property of binding to the mRNA of the highly expressed target gene so as to inhibit a cDNA extension reaction resulting from reverse transcriptase.

A method of determining a probability that a human test subject has colorectal cancer as opposed to not having colorectal cancer is disclosed. The method comprises, for each gene of a set of one or more genes selected from the group consisting of ANXA3, CLEC4D, IL2RB, LMNB1, PRRG4, TNFAIP6 and VNN1: determining a level of RNA encoded by the gene in blood of the test subject, thereby generating test data; providing positive control data representing levels of RNA encoded by the gene in blood of human control subjects having colorectal cancer, and providing negative control data representing levels of RNA encoded by the gene in blood of human control subjects not having colorectal cancer; and determining a probability that the test data corresponds to the positive control data and not to the negative control data, where the probability that the test data corresponds to the positive control data and not to the negative control data represents the probability that the test subject has colorectal cancer as opposed to not having colorectal cancer.

Provided herein are methods, oligonucleotides and peptide nucleic acids, compositions and kits for predicting a subject's response to treatment with activated protein C or protein C-like compound or susceptibility to major organ dysfunction or susceptibility to an inflammatory condition. The method generally comprises determining a genotype of said subject at one or more of polymorphic sites in the subject's protein C gene selected from one or more of the following: rs20069915 and one or more polymorphism sites in linkage disequilibrium thereto, selected from one or more of the following: rs2069910; rs2069916; rs2069924; rs2069931; rs1799808; rs2069920; and rs6714364 and may further involve comparing the determined genotype with known genotypes for the polymorphism that correspond with an improved response to treatment with activated protein C or protein C-like compound or correspond to susceptibility to major organ dysfunction or susceptibility to an inflammatory condition. Also provided are methods of treating subjects with an anti-inflammatory agent or anti-coagulant agent based on the subject's genotype.

The invention relates to a method for synthesising a bifunctional complex comprising an encoded molecule and an identifier polynucleotide identifying the chemical entities having participated in the synthesis of the encoded molecule, said method comprising the steps of i) providing a) at least one template comprising one or more codons capable of hybridising to an anti-codon, wherein said template is optionally associated with one or more chemical entities, and b) a plurality of building blocks each comprising an anti-codon associated with one or more chemical entities, and
ii) hybridising the anti-codon of one or more of the provided building blocks to the template, iii) covalently linking said anti-codons and/or linking the at least one template with the anti-codon of at least one building block, thereby generating an identifier polynucleotide capable of identifying chemical entities having participated in the synthesis of the encoded molecule, iv) separating the template from one or more of the anti-codons hybridised thereto, thereby generating an at least partly single stranded identifier polynucleotide associated with a plurality of chemical entities, v) generating a bifunctional complex comprising an encoded molecule and an identifier polynucleotide identifying the chemical entities having participated in the synthesis of the encoded molecule,
wherein said encoded molecule is generated by reacting at least two of said plurality of chemical entities associated with the identifier polynucleotide, and wherein said at least two chemical entities are provided by separate building blocks.

摘要:
The invention provides methods, nucleic acids, compositions and kits for predicting a subject's response to treatment with activated protein C or protein C like compound to identify subjects having a greater benefit from treatment with activated protein C. The method generally comprises determining a protein C pathway associated gene polymorphism genotype(s) of a subject for one or more polymorphisms in the these genes, comparing the determined genotype with known genotypes for the polymorphism that correspond with an improved response polymorphism to identify potential subjects having an inflammatory condition who are more likely to benefit from treatment with activated protein C or protein C like compound and subsequent to treatment recover from the inflammatory condition. The invention also provides for methods of treating such subjects with an anti-inflammatory agent or anti-coagulant agent based on the subject's genotype.
摘要:
An in vitro selection method is described which identifies oligonucleotide probes that discriminate amongst closely related nucleic acid sequences and which involves iterative hybridizations, including subtractive hybridization. Using the method, oligonucleotides are identified which can discriminate among human papilloma virus (HPV) subtypes. Corresponding methods and kits for the detection of nucleic acids are described, which methods and kits may be used in analytical, diagnostic, research and related applications.
