Abstract:
본 발명은 에스아이알엔에이(small interfering RNA; siRNA) 다중 접합체 및 이의 제조방법에 관한 것으로, 보다 상세하게는 이중가닥 센스/안티센스(sense/antisense) siRNA 단량체를 직접 또는 가교제나 고분자를 매개로 한 공유결합을 통해 연결시킨 (-X-A-)n의 구조식(여기서, X는 이중가닥 siRNA 단량체; A는 있거나 없을 수 있으며, 가교제 또는 고분자를 의미함; 및 n은 이중가닥 siRNA 단량체의 개수)을 가지는 siRNA 다중 접합체, 및 이의 제조방법에 관한 것이다. 본 발명의 siRNA 다중 접합체 제조방법은 그 반응이 간단하고 효율이 높으며, 상기의 방법으로 제조된 siRNA 다중 접합체는 기존 siRNA 비해 분자량이 수배 이상으로 크기 때문에 음이온 전하 밀도가 높아 양이온성 유전자 전달체와의 이온성 결합력이 우수하여 유전자 전달 효율을 현저히 높일 수 있다.

Abstract:
PURPOSE: A method for enrolling in classes using geographic information is provided to use mapped school geographic information and enables a user to visually perform enrollment in classes, thereby user can recognize accurate location information about the lectures. CONSTITUTION: A first lecture is selected when enrolling in classes by using online(S220). By using geographic information mapped with the selected first lecture, whether the selected first lecture is relevant to constraint condition of geographic information(S230). If the geographic information does not satisfies the first lecture, an announcement is outputted(S250). A finial selecting signal is received as considering the selected first lecture as a lecture of enrollment of classes. Signal selecting other lecture is received.
Abstract:
PURPOSE: A method for registering for courses by point allocation is provided to supply a change for enabling users to register for courses that the users want under fair conditions. CONSTITUTION: A lecture for course registration is selected(S220). Points are allocated within the limit of previously provided points for the selected lecture(S230). The same amount of points is assigned to all people who want to register for courses online. The points that the people hold are displayed. If points are allocated to the selected lecture, the points that the people hold are deducted.
Abstract:
PURPOSE: A siRNA multi-conjugate which targets multiple genes and a method for preparing the same are provided to improve gene delivery efficiency and to deliver siRNA of various sequences to cells. CONSTITUTION: A siRNA multi-conjugate which targets multiple genes has a structure formula 1(-(X1-A)n1 - (X2-A)n2 - (X3-A)n3 - (X3-A)n3 - ... - (Xi-A)ni-) or 2(x - A-(X1-A)n1 - (X2-A)n2 - (X3-A)n3 - (X3-A)n3 -...- (Xi-A)ni - x') which is connected through covalent bond of two or more kinds of double strand sense/antisense siRNA monomer with a crosslinking agent or polymers. The double strand sense/antisense siRNA monomer has 15-29 bases. The siRNA multi-conjugate targets surviving and Bcl-2. The multi-conjugate further contains a cell selective ligand at the end.
Abstract:
Disclosed are a controlled release gene delivery composition produced by solubilizing hydrophilic nucleic acid genes in an organic solvent and encapsulating the same in hydrophobic particles and a method for producing the same. The controlled release gene delivery composition according to an embodiment of the present invention comprises: a cationic and hydrophilic polymer grafted with hydrophobic molecules; and a gene composite which is produced by the bonding of genes on an organic solvent mixture. The cationic and hydrophilic polymer and gene composite are dispersed on the organic solvent so as to be easily encapsulated in nano particles.
