摘要:
It is intended to efficiently determine a base sequence specifically appearing in an expression gene. For this, providing that the expression gene consists of exons (301)...(306) and especially that exon (301) is united with exon (302) and exon (302) with exon (303), an aggregate of base sequences (401) (403) being a union of exon base sequences (301)...(305) and a boundary base sequence obtained by uniting together base sequences(404) and (405) and base sequences (406) and (407) respectively existing over boundaries between exon (301) and exon (302) and between exon (302) and exon (303) is formed, and the aggregate is searched. If a base sequence is one specifically appearing in the expression gene, the number of search results is 1 and otherwise, the number is plural.
摘要:
The present invention concerns a method for detecting the presence of a catalytically active ribozyme in a medium. The detection of the catalytically active ribozyme may be a goal by itself, or the ribozyme may serve as a reporter for the presence of other biomolecules in an assayed sample. The detection is carried out in a catalytic system wherein the presence of the active ribozyme serves to produce other active ribozyme in a positive-feedback amplificatory manner.

The invention provides novel and versatile classes of riboregulators, including inter alia activating and repressing riboregulators, switches, and trigger and sink RNA, and methods of their use for detecting RNAs in a sample such as a well and in modulating protein synthesis and expression.

The invention provides amplification-based methods for detecting hypermethylated or hypomethylated nucleic acid in heterogeneous biological samples, e.g., stool. A screening procedure based on the detection of hypermethylation, preferably at multiples genes, provides a means for detecting various diseases, e.g., colorectal cancer. By using chimeric primers that contain a 5' non-specific portion, the specificity and efficiency of the nucleic acid amplification is improved. Methods of the invention are especially useful in detection of rare events in a heterogeneous sample.

Provided are the use of collections of binding proteins, called capture agents, and their cognate binding partners, called tagged protein libraries, herein for profiling samples. Methods for generating the capture agents, tagged protein libraries and samples are also provided.

A method of identifying putative naturally occurring antisense transcripts is provided. The method is effected by (a) computationally aligning a first database including sense-oriented polynucleotide sequences with a second database including expressed polynucleotide sequences; and (b) identifying expressed polynucleotide sequences from the second database being capable of forming a duplex with at least one sense-oriented polynucleotide sequence of the first database, thereby identifying putative naturally occurring antisense transcripts.
摘要:
This application provides methods of detecting and quantitatively determining a target nucleic acid sequence in a sample, which comprise contacting the sample with a primer and a zymogene which encodes, but which itself is the anti-sense sequence of, a catalytic nucleic acid sequence, so that when the target is present, a single amplified nucleic acid molecule is produced which comprises the sequences of both the target and catalytic molecules. This invention further provides a method of simultaneously detecting the presence of a plurality of target nucleic acid sequences in a sample. Finally, this invention provides molecules and kits for practicing the instant methods.
