标 题:Cyclodextrin labels for nucleic acid and biochemical analysis
发明人：KOSAK KENNETH M
权利人:KOSAK KENNETH M
摘要:This invention provides a method of qualitative and quantitative nucleic acid sequence analysis using luminescent cyclodextrin (CD), labels for dideoxy-nucleotide chain terminators and oligonucleotide primers. The CD labels are nonradioactive and detected in a ''black'' background, avoiding problems of fluorescence and allowing more sensitivity. Through formation of inclusion complexes with various fluorophores, the CD labels provide the versatility of different colored labels, with potentially higher signal efficiency in aqueous solutions. The CD labels have similar structures and thereby provide simplicity of synthesis and use, with more uniform chemical/physical properties, even with different colored labels. The invention is intended for high volume nucleic sequencing employing photomultipliers or charge-coupled device cameras for detection. Through the combination of these features, this invention provides advantages of speed, sensitivity, simplicity and versatility previously unknown or suggested in the art of nucleic acid sequence analysis.

摘要:This invention relates to the field of novel explosives, compositions and munitions comprising the same, as well as methods of synthesis and their use. The invention particularly relates to the field of explosives which are switchable between two different liquid crystalline states, and which possesses a general formula below. n n n n n n n n n n wherein M is a mesogenic core, R 1 and R 2 are independently selected terminal end groups attached to the mesogenic core, and wherein the mesogenic core contains sufficient (NO 2 ) x to provide an explosive output. The explosive compound may form part of an explosive composition, which may be used as a high explosive fill for any part of a munition. The explosive composition may contain other components such as non-explosive LC compounds, or binders, or further known explosive compounds. The explosive composition has one or more liquid crystalline states, which may possess differing sensitivities
