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 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:
Methods of identifying molecular interaction sites in eukaryotic and prokaryotic nucleic acids, especially RNA, are described. Secondary structural elements are identified from highly conserved sequences. Methods of preparing databases relating to such molecular interaction sites are also provided herein as are databases themselves. Therapeutic, agricultural, industrial, and other applicability results from interaction of such molecular interaction sites with “small” and other molecules.

Methods for detecting and identifying unknown bioagents, including bacteria, viruses and the like, by a combination of microRNA containing nucleic acid amplification and molecular weight determination using primers which hybridize to conserved sequence regions of microRNA containing 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) or molecular mass which is then matched against a database of base composition signatures or molecular masses, by which the species of 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:
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.
摘要:
The present invention provides methods for the identification of target molecules that bind to ligands, particularly microRNA ligands and mimics thereof and/or microRNA target molecules and mimics thereof, with as little as millimolar (mM) affinity using mass spectrometry. The methods may be used to determine the mode of binding interaction between two or more of these target molecules to the ligand as well as their relative affinities. Also provided are methods for designing compounds having greater affinity to a ligand by identifying two or more target molecules using mass spectrometry methods of the invention and linking the target molecules together to form a novel compound.
