    摘要: The present invention provides methods for the determination of the structure of biomolecular targets, as well as the site and nature of the interaction between ligands and biomolecular targets. The present invention also provides methods for the determination of the relative affinity of a ligand for the biomolecular target it interacts with. Also provided are methods for screening ligand or combinatorial libraries of compounds against one or more than one biological target molecules. The methods of the invention also allow determination of the relative binding affinity of combinatorial and other compounds for a biomolecular target. The present invention further provides methods for the use of mass modifying tags for screening multiple biomolecular targets. In a preferred embodiment, ligands which have great specificity and affinity for molecular interaction sites on biomolecules, especially RNA can be identified. In preferred embodiments, such identification can be made simultaneously with libraries of ligands.

    摘要: The present invention provides an aptamer or pool of aptamers (nucleic acid sequences) that bind(s) to a target molecule on the surface, accessible from the surface or inside of a mammalian sperm cell and a method for producing the aptamers. The method comprises contacting a collection of different nucleic acid molecules with the target molecule under conditions favorable for binding between at least one of the nucleic acid molecules and the target molecule, to form at least one complex comprising the nucleic acid molecule bound to the target molecule, wherein each of the nucleic acid molecules comprises at least one segment of randomized nucleotide sequences. The complexes are then separated from the unbound nucleic acid molecules and unbound target molecules, and the bound nucleic acid molecule is recovered from the separated complex. The aptamers are used to separate sperm cells based upon sperm cell qualities, such as whether the cells contain X chromosomes or Y chromosomes.

    摘要: The present invention provides novel algorithms for designing oligonucleotides that do not substantially hybridize to a small group of unwanted transcripts, while hybridizing to most other transcripts. Such oligonucleotides are particularly useful as primers for reverse transcription. The invention also provides compositions containing oligonucleotides that do not substantially hybridize to a small group of unwanted transcripts, while hybridizing to most other transcripts.

    摘要: Probes and methods of using the probes to detect chromosomal rearrangements and/or deletions are provided. The methods utilize probes that are free of repeat sequences to provide greater selectivity and sensitivity; methods for producing such probes are also disclosed. The probe sets utilized in the detection methods are designed to hybridize to chromosomes at regions outside known breakpoints, instead of spanning the breakpoint as with conventional FISH methods, and, in some instances, are further designed to bind to regions located outside the genes involved in the rearrangement. Methods utilizing probe sets with two and four colors are also described, as are automated methods for analyzing rearrangements.
