标题:电压敏感染料对大脑中特定细胞和分子的化学靶向
摘要:电压敏感荧光染料 (Vsd) 是探测神经元和其他可兴奋细胞中信号转导的重要工具.然而,由于在脑组织或活体动物中缺乏细胞特异性靶向方法,这些高度亲脂性传感器的影响受到限制.我们通过引入非遗传分子平台来解决这一关键挑战,用于大脑中合成 Vsd 的细胞和分子特异性靶向.我们采用葡聚糖聚合物颗粒,通过动态封装和高亲和力配体克服 Vsd 固有的亲脂性,仅在生理表达水平上利用神经传递机制的天然成分将构建体靶向特定神经元细胞.二氯烷,一种单胺转运蛋白配体,能够靶向小鼠纹状体中密集的多巴胺能轴突和急性脑切片中小鼠皮层中稀疏的去甲肾上腺素能轴突.pfqx 与配体导向的酰基咪唑化学相结合,能够在相同的大脑区域中对 Ampa 型谷氨酸受体进行共价标记.带有经典电致变色 Anep 染料或最先进的电压氟型染料的探针变体以与母体染料类似的方式响应膜电位变化,如全细胞贴片记录所示.我们用单光子和双光子荧光显微镜证明了用

标 题:DNA-reporter conjugates linked via the 2' or 5'-primary amino group of the 5'-terminal nucleoside
发明人：SMITH LLOYD M; FUNG STEVEN; KAISER JR ROBERT J
权利人:CALIFORNIA INST OF TECHN
摘要:The invention consists of compounds and methods for the synthesis of oligonucleotides which contain one or more free aliphatic amino groups attached to the sugar moieties of the nucleoside subunits. The synthetic method is versatile and general, permitting amino groups to be selectively placed at any position on oligonucleotides of any composition or length which is attainable by current DNA synthetic methods. Fluorescent dyes or other detectable moieties may be covalently attached to the amino groups to yield the corresponding modified oligonucleotide.

权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:Methods for the automated template-free synthesis of user-defined sequence controlled biopolymers using microfluidic devices are described. The methods facilitate simultaneous synthesis of up to thousands of uniquely addressed biopolymers from the controlled movement and combination of regents as fluid droplets using microfluidic and EWOD-based systems. In some forms, biopolymers including nucleic acids, peptides, carbohydrates, and lipids are synthesized from step-wise assembly of building blocks based on a user-defined sequence of droplet movements. In some forms, the methods synthesize uniquely addressed nucleic acids of up to 1,000 nucleotides in length. Methods for adding, removing and changing barcodes on biopolymers are also provided. Biopolymers synthesized according to the methods, and libraries and databases thereof are also described. Modified biopolymers, including chemically modified nucleotides and biopolymers conjugated to other molecules are described.

标 题 :Solid support for synthesis of 3'-tailed oligonucleotides
发明人：REED MICHAEL W; MEYER JR RICH B; PETRIE CHARLES R; TABONE JOHN C
权利人:MICROPROBE CORP
摘要:A solid support for oligonucleotide synthesis has the structure where CPG represents a controlled pore glass matrix, the wavy line represents a carbon chain covalently linking the NH group with the controlled pore glass matrix, X is 2,2'-dimethoxytrityl or H, and R is alkyl, aryl, arylalkyl, heteroalkyl, or heteroaryl. The dimethoxytrityl group is removed from the solid support by treatment with acid, and the oligonucleotide is built, step-by-step in a conventional synthesizer after attachment of the 3' end of the first oligonucleotide unit to the hydroxyl function connected to the R group.

摘要:The present invention provides modified cycloalkyne compounds; and method of use of such compounds in modifying biomolecules. The present invention features a cycloaddition reaction that can be carried out under physiological conditions. In general, the invention involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).
