20120015354 | NUCLEIC ACID APTAMER BINDER SPECIFICALLY TO BISPHENOL A - A nucleic acid aptamer capable of binding specifically to bisphenol A and a method of detecting and removing bisphenol A using the nucleic acid aptamer. The nucleic acid aptamer capable of binding specifically to bisphenol A has affinity for bisphenol A at nM concentration, and thus can detect even a very small amount of bisphenol A. Also, the nucleic acid aptamer can specifically detect only bisphenol A without showing affinity for other bisphenols, including bisphenol B having no difference from bisphenol A except for a single methyl group. Accordingly, the nucleic acid aptamer is effective in detecting and removing the environmental hormone bisphenol A which is difficult to detect by conventional methods. | 01-19-2012 |
20120028811 | DEVICE FOR RAPID IDENTIFICATION OF NUCLEIC ACIDS FOR BINDING TO SPECIFIC CHEMICAL TARGETS - The present invention relates to microfluidic chips and their use in SELEX. The microfluidic chip preferably includes a reaction chamber that contains a high surface area material that contains target. One preferred high surface area material is a sol-gel derived material.

20120040865 | TARGET SUBSTANCE DETECTION METHOD USING APTAMER - The present invention relates to a method and kit of detecting a target material using an aptamer, and more particularly to a method and kit for detecting a target material, in which a sample and a second aptamer are added to a first aptamer immobilized on a solid phase so as to form a bond sandwiched between the first aptamer, the target material and the second aptamer, to an FET sensor-based method and kit for detecting a target material, and to an AAO sensor-based method and kit for detecting a target material. | 02-16-2012 |
20120129722 | METHOD FOR SCREENING NEW DRUG CANDIDATE INHIBITING TARGET PROTEIN-PROTEIN INTERACTION FOR DEVELOPMENT OF FIRST-IN-CLASS DRUG - The present invention relates to a method for screening a substance inhibiting protein-protein interactions, and more particularly to a method for screening a substance inhibiting protein-protein interactions, the method comprising using a protein chip having immobilized thereon spots comprising a mixture of a sol-gel material and a protein. According to the invention, a protein chip can be easily manufactured in a 96-well plate using a sol-gel material, whereby an inhibitor that inhibits protein-protein interactions can be easily screened from a library of natural substances. | 05-24-2012 |
20130210637 | SOL-GEL CHIP USING POROUS SUBSTRATE FOR ENTRAPPING SMALL MOLECULES AND SCREENING METHOD OF SMALL MOLECULES SPECIFIC MATERIAL USING THEREOF - There is provided a sol-gel chip using a porous substrate for entrapping small molecules and a method for screening a small molecule-specific material using the same, and more particularly, a porous substrate sol-gel chip characterized in that a sol-gel composition for entrapping small molecules is spotted on a surface of the porous substrate, a method for manufacturing the porous substrate sol-gel chip for entrapping small molecules, and a method for screening a material specifically binding to the small molecules using the porous substrate sol-gel chip for entrapping small molecules. | 08-15-2013 |
20130274113 | MULTIPLEX MICROFLUIDIC DEVICE FOR SELECTING NUCLEIC ACID APTAMERS, AND HIGH THROUGHPUT SELECTION METHOD FOR NUCLEIC ACID APTAMERS USING SAME - The present invention relates to a multiplex microfluidic device for selection of nucleic acid aptamers and a method for high-throughput selection of nucleic acid aptamers using the same, and more particularly to a multiplex microfluidic device (SELEX lap-on-a-chip) that uses an improved multiplex platform in place of the development of an aptamer for a single target and to a method for high throughput selection of aptamers using the same together with high-throughput sequencing. A multiplex microfluidic device according to the present invention can simultaneously detect aptamers for a plurality of targets, and it can greatly increase the screening throughput and greatly shorten the process time compared to conventional multiplex techniques. Particularly, when a process for selecting aptamers is performed using the device of the invention together with a high-throughput sequencing method, the number of target binding/elution/amplification rounds can be greatly reduced, and the process can be performed in an automated manner. Thus, the device of the invention is highly useful. | 10-17-2013 |
