    摘要: The invention concerns fluorescence standards, and in particular fluorescence standards for calibrating optical detectors. According to the invention, a fluorescent mineral or mixtures of minerals are employed for use as a fluorescence standard. The fluorescent mineral can be a naturally occurring mineral or a synthetically produced mineral. Preferred fluorescent minerals for use as fluorescence standards are corundum, fluorite, turquoise, amber, zircon, zoisite, iolite or cordierite, spinel, topaz, calcium fluorite, sphalerite or zincblende, calcite or calcspar, apatite, scheelite or calcium tungstate, willemite, feldspars, sodalite, a uranium mineral, a mineral containing Al3+, and in particular ruby and sapphire.

    摘要: Methods and kits for detecting a target nucleic acid in a sample are described. In some embodiments, the sample to be analyzed includes a primer which hybridizes to at least a portion of the target nucleic acid, a probe having a first region which hybridizes to at least a portion of the target nucleic acid and a second region having a detectable label, a polymerase which extends the hybridized primer and an enzyme comprising nuclease activity that can cleave the hybridized hybridization probe to thereby release a labeled probe fragment. In some embodiments, the sample can then be contacted with a solid support comprising surface bound capture probes which can hybridize to the labeled probe fragment(s). These capture probes more readily bind to the probe fragment(s) than to the intact hybridization probe. The label can then be detected on the support surface. In this manner, improved discrimination between the probe fragments and the intact hybridization probes can be achieved.

    摘要: The current teachings are directed to compositions, methods, and kits for selectively amplifying and for detecting target sequences. In some embodiments, a circularizable probe and/or a probe pair are disclosed for selectively amplifying target sequences. Methods for selectively amplifying target sequences are also disclosed, as are methods for detecting selectively amplified target sequences. Certain embodiments of the disclosed methods comprise a circularizable probe, a probe pair, comprising a first probe and a second probe, or both. In certain embodiments, a multiplicity of different circularizable probes, a multiplicity of different probe sets, or a multiplicity of different circularizable probes and a multiplicity of different probe sets are provided to selectively amplify or to detect a multiplicity of different target sequences, typically in a multiplex reaction. According to certain disclosed methods, surrogates of the target sequences are selectively amplified, including without limitation ligated probes, first amplification products, second amplification products, or combinations thereof. In some embodiments, selectively amplified target sequences or their surrogates are detected, directly or indirectly, indicating the presence of the corresponding target sequence. Kits to facilitate the performance of the disclosed methods are also provided.

    摘要: The invention relates to 5′-modified nucleotides and to nucleic acids which contain these nucleotides. Processes for incorporating the 5′-modified nucleotides into nucleic acids, and the subsequent site-specific cleavage of the nucleic acids at the 5′-modified monomer building blocks, are also disclosed. These processes can be employed for nucleic acid sequencing, for generating nucleic acid libraries, for detecting mutations, for preparing support-bound nucleic acids and for pharmaceutical purposes.
