7-Triazolylcoumarin-based fluorescent tag system for stepwise, comparative assessment of small molecule microarrays
摘要:
The potential use of a fluorescent tag system based on 7-(1H-1,2,3-triazol-4-yl)coumarin fluorophore having a fluorous moiety and a polyethylene glycol (PEG) spacer at opposite ends as a tool for a stepwise and comparative evaluation of the fabrication process of small molecule microarrays was illustrated by the qualitative analysis of the results of the fluorescence detection obtained from the microarray experiments using the tagged biotins and streptavidin-Cy3 (and avidin-Cy5) as the binding partners.

F-烷基化试剂的反应,包括(全氟烷基)烷基卤化物和磺酸盐[R fn(CH 2)m X(X = Br,I,OTs,OTf)],以及在100°C DMSO中略有过量的NaN 3保持5小时,然后进行水蒸气蒸馏,以高纯度(GC测定≥98%)高至极好产率分离出叠氮化物R fn(CH 2)m N 3。由于这些氟叠氮化物的稳定性,它们可以在大气压或更低的压力下蒸馏以进一步纯化。4-叠氮全氟甲苯(p- CF 3 C 6 F 4 N 3)和1-叠氮辛烷也分别在相似的条件下从全氟甲苯(CF 3 C 6 F 5)或1-碘辛烷开始制备。蒸汽蒸馏可以轻松安全地分离出高达50 g的产品。
Synthesis of modified monosaccharides, derivatives of glucose and galactose, having a highly fluorinated chain, as a library of synthetic buildingblocks for hyaluronicacid (HA) modified subunits has been developed. “Click” chemistry has been employed as a strategy for the synthesis of these molecules. 1,2,3-triazole ring derivatives were obtained with good to excellent yields.

A heterotrifunctional template was developed that utilizes thiol–maleimide and click chemistries (both copper-free and copper-mediated) to effect sequential biomolecule conjugations in a one-pot process. The breadth of compatible substrates was illustrated through highly efficient conjugations of protein, peptide, sugar, lipid, fluoroalkane, biotin and fluorophore molecules. This template should be useful for the creation of chemically-enhanced/enabled biotherapeutics, especially through the expression of discontinuous (and heterogeneous) epitopes.

The present invention is a method for the characterization or detection of one or more antibodies in a sample. The method comprises obtaining a tagged antigen comprising an antigen and a mass tag attached to the antigen. The tagged antigen has specificity for the antibody. In addition, the method comprises combining the tagged antigen with the antibody to form a tagged antigen-antibody complex. Further, the method comprises cleaving the mass tag from the tagged antigen-antibody complex. Thereafter, the method comprises analyzing the mass tag via a mass spectrometer to determine the presence of the mass tag in the sample and correlating the presence of the mass tag with a presence of the antibody in the sample.
