Abstract:
PURPOSE: A derivative from CD9-specific human antibody is provided to ensure high binding affinity to CD9 and to use as an in vivo imaging antibody and in vivo diagnosis. CONSTITUTION: An anti-CD9 tetravalent antibody which is connected by disulfide bond of anti-CD9 bivalent antibody short chain contains anti-CD9 bivalent scFv of sequence number 15 and human antibody Fc. A composition for detecting caner of CD9 overexpression contains diagnostically effective amount of anti-CD9 tetravalent. The cancer is stomach cancer, adenocarcinomas or ovarian cancer.
Abstract:
Disclosed is a method for manufacturing an aluminum-fine carbon material composite. In order to manufacture the aluminum-fine carbon material composite, first of all, aluminum powder and the fine carbon material are dispersed so as to obtain a powder mixture of the aluminum-fine carbon material. Then, the powder mixture of the dispersed aluminum-fine carbon material is sintered and shaped. Thereafter, the sintered composite of the aluminum-fine carbon material is extruded with heat. According to the method for manufacturing the aluminum-fine carbon material composite, the aluminum-fine carbon material composite with excellent heat insulation and mechanical properties can be manufactured by a relatively simple process.

본 발명은 탄소나노튜브를 이용한 면상발열체 및 이의 제조방법에 관한 것으로 좀 더 상세하게는 (a) 탄소재료를 산성 용액 하에서 초음파 처리하여 탄소재료에 기능기를 부착시키는 단계; 및 (b) 분산된 탄소재료를 고분자 화합물과 혼합시키는 단계를 포함하는 면상발열체의 제조 방법에 관한 것이다. 본 발명에 의하면 탄소나노튜브와 바인더 간의 적절한 혼합비율로 인하여 기존의 것보다 열효율이 높으며 저항 변화가 적은 면상발열체를 제공할 수 있다.
Abstract:
본 발명은 CD9-특이적인 인간 항체에 관한 것으로, 보다 상세하게는 CD9에 특이적으로 결합하는 인간으로부터 유도된 상보성 결정 영역(complementarity determining region, CDR)과 프레임 워크 영역(framework region, FR)으로 구성된 인간 항체에 관한 것이다. 본 발명의 인간 항체는 CD9에 특이적으로 결합하고, CD9 항원에 대해 중화 효능(neutralizing effect)이 있으며, 암 세포주에서 억제 효능이 있음을 확인함으로써 CD9 과발현 암에 대한 예방 및 치료제로 유용하게 사용될 수 있다.

Abstract:
PURPOSE: A CD9-specific human antibody is provided to suppress cancer cell line and prevent and treat CD9 overexpressed cancer. CONSTITUTION: A CD9-specific human antibody contains a heavy chain having variable region with HCDR and light chain having variable region with LCDR. A method for preparing the CD9-specific human antibody comprises: a step of preparing an expression vector having a gene encoding a polypeptide corresponding to a fragment having immunological activation of light chain and heavy chain; a step of introducing the expression vector to a host cell to prepare a transformant; a step of culturing the transformant; and a step of isolating antibodies from the culture medium. A pharmaceutical composition for preventing and treating gastric cancer or ovarian cancer contains the CD9-specific human antibody.
