摘要:
The invention relates to compositions and methods for detection of nucleic acid sequences. The invention further relates to kit format of said compositions for detection of nucleic acid sequences. Oligonucleotide probes of the invention comprise a target binding sequence and a sequence at least partially complementary thereto, joined by an optional linker to form a hairpin structure in the absence of the target nucleic acid sequence. The probes of the invention comprise a pair of moieties that produce a detectable signal when the probe hybridizes to the target sequence.
摘要:
The present invention provides compositions, kits, and methods for detecting polynucleotide sequence differences. The method involves amplifying a polynucleotide in the presence of a labeled nucleotide whose incorporation into the amplified product can indicate the presence of a sequence difference within the polynucleotide template. The invention is particularly useful for differentiating two or more closely related polynucleotide sequences, for example, in determining which allele or alleles of a multiallelic organism are present in a target polynucleotide.

The present invention relates, in part, to control nucleic acid molecules having no significant sequence homology to any known nucleic acid, and predefined G/C-content. The present invention further relates to method of using control nucleic acid molecules to validate microarray analyses, compositions comprising control nucleic acid molecules, and kits comprising control nucleic acid molecules.
摘要:
The invention relates to novel platinum-based compounds for labeling biomolecules. Platinum based labeling compounds according to the invention irreversibly attach to a target biomolecule via coordination of a platinum (II) metal center with N or S atoms on the target biomolecule. The invention relates to the novel compounds themselves, methods of making the platinum-based labeling compounds, probes labeled with such compounds, methods of making such labeled probes, and kits comprising the novel platinum-based labeling compounds and/or probes labeled with them. The invention also relates to methods of using probes labeled with platinum-based labeling compounds of the invention, particularly array and microarray hybridization methods.
摘要:
A method in which a temperature is generated across a gradient block, and an apparatus comprising a block (2, 17, 18, 19) across which a temperature gradient can be generated. By setting up such a gradient, multiple reaction mixtures held in wells (3) on the gradient block (2, 17, 18, 19) can be simultaneously run at temperatures which differ only slightly, thereby permitting an optimum temperature for the reaction to be quickly identified. In a preferred embodiment, the gradient block (2, 17, 18, 19) is integrated into a thermal cycler used for nucleic acid amplification reactions.
