摘要:
Polynucleotides comprising molecular interaction sites of 16S rRNA that have particular secondary structure are provided. Methods of using such polynucleotides to screen, virtually or actually, combinatorial libraries of compounds that bind thereto are also provided. Method of modulating the activity of 16S rRNA by contacting 16S rRNA or prokaryotic cells containing the same with a compound identified by such virtual or actual screening are also provided.

The present invention provides design and synthesis of oligomeric compounds and compositions that can be administered to reduce the activity of SARS virus in vivo or in vitro, to prevent or treat SARS virus-associated disease, to detect AARS virus, and to diagnose SARS virus-associated diseases.
摘要:
The present invention provides a method for rapid identification and quantitation of bacteria by amplification of a segment of bacterial nucleic acid followed by analysis by mass spectrometry. The compositions provide for characterization of the molecular masses and base compositions of bacterial nucleic acids which are used to rapidly identify bacteria.
摘要:
Method for detecting and identifying unknown bioagents, including bacteria, viruses and the like, by a combination of nucleic acid amplification and molecular weight determination using primers which hybridize to conserved sequence regions of nucleic acids derived from a bioagent and which bracket variable sequence regions that uniquely identify the bioagent. The result is a “base composition signature” (BCS) which is then matched against a database of base composition signatures, by which the bioagent is identified.
摘要:
The present invention provides methods for rapid forensic investigations by identification of bioagents associated with biowarfare and acts of terrorism or crime. The methods are also useful for epidemiological investigations by genotyping of bioagents.
摘要:
The present invention relates generally to the field of investigational bioinformatics and more particularly to secondary structure defining databases. The present invention further relates to methods for interrogating a database as a source of molecular masses of known bioagents for comparing against the molecular mass of an unknown or selected bioagent to determine either the identity of the selected bioagent, and/or to determine the origin of the selected bioagent. The identification of the bioagent is important for determining a proper course of treatment and/or irradication of the bioagent in such cases as biological warfare. Furthermore, the determination of the geographic origin of a selected bioagent will facilitate the identification of potential criminal identity.

摘要:
The method described herein relate generally the identification of bioagents on the basis of base composition signatures for bioagent-identifying amplicons. Specifically, methods of the present invention are directed to the application of pattern recognition models, particularly probability pattern classifiers, to the identification of both known and previously unrecognized bioagents. In certain embodiments, the pattern classifiers relate to probability cloud patterns, such as mutational probability patterns. In other embodiments the pattern classifiers relate to polytope pattern models.
摘要:
There is a need for nucleic acid analysis which is both specific and rapid, and in which no nucleic acid sequencing is required. The present invention addresses this need, among others by providing a method of nucleic acid amplification of overlapping sub-segments of a nucleic acid followed by molecular mass measurement of resulting amplification products by mass spectrometry, and determination of the base compositions of the amplification products.
