摘要:描述了在溶液和刚性基质条件下使用芳氧基草酰氯(aoc),芳氧基草酰叔丁基过氧化物(aob)和草酸二芳基酯(dao)来单分子生成苯氧基基团的现象.Aoc可用于光化学生成苯氧基自由基,但仅当使用2,6-二叔丁基化衍生物时,才能方便地稳定用作前体.Aob可用作芳氧基的热前体,因为它们通常会在60-85摄氏度下2-3小时内分解以产生酚.(1)h-NMR溶液动力学研究发现,对于苯氧基草酰叔丁基过氧化物的分解,Deltah()= 31 Kcal / Mol,Deltas()= +3.4 Cal / Mol-K,这与过氧化物键断裂的基本一致一致.Aob和更稳定的dao也是方便的光化学苯氧基自由基前体.

标 题:Cyclodextrin labels for nucleic acid and biochemical analysis

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.
