Liquid-liquid extraction of enzymatically synthesized functional RNA oligonucleotides using reverse micelles with a DNA-surfactant.

چکیده
We successfully implemented solvent extraction of short, single-stranded RNA using reverse micelles (water-in-oil microemulsions) with a DNA-surfactant. A thrombin-binding RNA aptamer was enzymatically synthesized and purified by extraction using the reverse micellar system. The extracted RNA aptamer retained thrombin-binding activity after the extraction procedure.

Sequence-selective extraction of single-stranded DNA using DNA-functionalized reverse micelles.
We report here sequence-specific liquid/liquid extraction of single-stranded DNA using reverse micelles (water-in-oil microemulsions), in which hybridization between a DNA-surfactant and a target DNA having a complementary sequence allows selective transport of the target DNA to an organic phase from a mixture of DNA oligonucleotides.
متن کاملSeparation of pharmaceutical products with reverse micelles
Reverse micelle extraction has received considerable attention in recent years due to its ability to selectively solubilise solutes from an aqueous phase and to maintain their biological activities. This paper presents the results from studies on extraction of penicillin G from aqueous solution (forward extraction) and from reverse micelles to a new aqueous solution (backward extraction), by em...
متن کاملSurfactant-enhanced liquid-liquid extraction in microfluidic channels with inline electric-field enhanced coalescence.
Continuous microfluidic liquid-liquid extraction is realized in a microfluidic device by generating emulsions with large interfacial areas for mass transfer, and subsequently breaking these emulsions using electric fields into easily separated segments of immiscible liquids (plugs). The microfluidic device employs insulated electrodes in a potassium hydroxide-etched channel to create large elec...
متن کاملA New Thermodynamic Approach for Protein Partitioning in Reverse Micellar Solution
Reverse micellar systems are nanofluids with unique properties that make them attractive in high selectivity separation processes, especially for biological compounds. Understanding the phase behavior and thermodynamic properties of these nanosystems is the first step in process design. Separation of components by these nanosystems is performed upon contact of aqueous and reverse micellar phase...
متن کاملInteraction and micellar behavior of aqueous mixtures of surface active ionic liquid and cationic surfactant: experimental and theoretical studies
The interaction between an ionic liquid (1-dodecyl-3-methylimidazolium bromide or IL) and cationic surfactant (dodecyltrimethylammonium bromide (DTAB)) in aqueous solution has been investigated at various mole fractions and temperature 30 ˚C using experimental and theoretical methods. The critical micelle concentration (CMC) of pure components and their binary mixtures, mixed micellar compositi...
