Abstract:
본발명은나노와이어를이용하여세포내에서생체물질을포획또는포획된생체물질을세포밖으로분리함으로써세포를용해하지않고세포내에서의생체물질또는생체물질들의상호작용을검출하는방법에관한것이다. 본발명은, 세포내의특정생체물질과특이적으로결합하는리간드가결합된나노와이어를이용하여생체물질을포획하고세포밖으로분리시킨후 나노와이어에남아있는생체물질을분석하는방법을제공할수 있다. 또한세포를파괴하지않고특정생물질을포획하여세포밖으로제거함으로써일어나는세포의변화를관찰하는데에도용이하게활용할수 있다.
Abstract:
PURPOSE: A manufacturing method of polyacrylonitrile copolymer for molding carbon fibers is provided to increase the speed of a polymerization of a polyacrylonitrile with a high yield and to reduce a by-product and a deteriorated product by using a microwave for heating. CONSTITUTION: A manufacturing method of polyacrylonitrile copolymer for molding carbon fibers comprises: a step manufacturing a composition including a monomer, a 0.01-1 wt% initiator, and a solvent; and a step radiating a microwave to the composition. The monomer is acrylonitrile monomer and one or more monomer selected from a group consisting of a methyl acrylate, a methacrylic acid and an itaconic acid. The initiator is 2,2'-azobis isobutyronitrile or a MEKP[methyl ethyl ketone peroxide]. The solvent is selected from the group of a dimethyl sulfoxide, a dimethylformamide, and formic acid.

Abstract:
본 발명은 형광 에너지 전달 (Fluorescence Resonance Energy Transfer; FRET) 방법을 이용하여 세포 내에서의 HIF-1α와 p300 단백질 간의 결합을 실시간으로 정량 분석하는 방법 및 상기 방법을 이용하여 HIF-1α와 p300 단백질 결합 억제제 또는 촉진제를 실시간으로 세포내에서 스크리닝하는 방법에 관한 것이다. 보다 구체적으로, 본 발명은 형광 에너지를 전달해주는 공여체 (donor, 예컨대, ECFP)를 C-말단에 표지한 p300과 형광 에너지를 전달받는 수여체 (acceptor, 예컨대, EYFP)를 C-말단에 표지한 HIF-1α 간의 에너지 전달 효율로부터 두 단백질의 결합 정도를 정량적으로 분석하는 방법을 제공한다.
Abstract:
PURPOSE: A real time analysis method of the interaction between HIF-1alpha and p300 protein is provided to quantitatively analyze the interaction between HIF-1alpha and p300 protein in real time at a cellula level using a fluorescence resonance energy transfer method and to screen the interaction in a cell in real time. CONSTITUTION: A method for measuring the interaction between HIF-1alpha and p300 protein comprises the steps of: preparing an HIF-1alpha plasmid containing HIF-1alpha of which N terminal, C terminal, or the both terminals is (are) labeled with a first fluorescent material; preparing a p300 protein plasmid containing p300 protein of which N terminal, C terminal, or both terminals is (are) labeled with a second fluorescent material; injecting the prepared HIF-1alpha plasmid and p300 plasmid into eukaryotes; and measuring the fluorescence generated from the transfected cells and calculating the fluorescence transfer efficiency according to equation (FRET index = I_DA- (a_DI_DA)- (a_AI_DA), FRET efficiency = FRET index/255). One of the first and second fluorescent materials is a fluorescent energy donor and the other is a fluorescent energy acceptor. The fluorescence spectrum of the fluorescent energy donor and the fluorescent energy acceptor is partially or entirely overlapped.
