Patent number: 11953502Abstract: The present invention relates to an epitope of a thioredoxin-1 (Trx1) antigen and a use thereof, and more particularly, to the epitope, and an antibody or an antigen-binding fragment binding thereto. The epitope region of the human Trx1 antigen confirmed in the present invention may be effectively used in the development of an improved antibody to enhance the binding affinity of an anti-Trx1 antibody. In addition, the improved antibody of the present invention is effective in improvement of performance of a breast cancer diagnosis kit due to excellent binding affinity for Trx1 and very high sensitivity and specificity, compared to a conventional anti-Trx1 antibody. Further, the accuracy and reliability of breast cancer diagnosis may significantly increase because exceptionally high sensitivity and specificity are exhibited by detecting the monoclonal antibody of the present invention, which specifically binds to Trx1, rather than detecting CA15-3, another conventional breast cancer diagnostic biomarker.Type: GrantFiled: October 12, 2018Date of Patent: April 9, 2024Assignee: E&S HEALTHCARE CO., LTD.Inventors: Kyong Hoon Suh, Dae Joong Kim, Young Kim, Mi Kyung Kim, Jong Hwan Jung, Ki Se Lee

Patent number: 8067341Abstract: Carbon nanotube (CNT) films, patterns and biochips and methods of making the same are provided. Such a biochip comprises a bio-receptor attached by means of an exposed chemical functional group on a surface of a high density CNT film or pattern produced by repeated lamination of CNTs on a substrate with exposed amine groups. Various types of CNT-biochips may be fabricated by bonding of bio-receptors to a CNT pattern (or film) containing exposed carboxyl groups or modified by various chemical functional groups. Further, the CNT-biochip may be used to measure an electrical or electrochemical signal using both conductor and semiconductor properties of the CNT, thereby not needing labeling. Upon fluorescent measurement of DNA hybridization using such a CNT-DNA chip it is possible to show more distinct signals useful for genotyping, mutation detection, pathogen identification and the like.Type: GrantFiled: March 19, 2004Date of Patent: November 29, 2011Inventors: Hee Tae Jung, Sang Yup Lee, Dae Hwan Jung, Byung Hun Kim, Young Koan Ko

Patent number: 7670831Abstract: Conductive carbon nanotubes (CNTs) obtained by dotting carboxylated CNTs with metal nanocrystals by chemical functional groups, are described, as well as a method for fabricating a pattern or film of the conductive CNTs which involves repeatedly depositing conductive CNTs on a substrate to achieve high surface density. A biosensor is described, in which bioreceptors that bind to target biomolecules are selectively attached to conductive CNTs or a conductive CNT pattern or film. By use of the conductive biosensor, various target biomaterials that bind or react with the bioreceptors can be precisely measured directly or by electrochemical signals at large amounts in one step. Additionally, the biosensor can be used for an electrical detection method capable of providing precise measurement results even with a small amount of source material.Type: GrantFiled: June 3, 2004Date of Patent: March 2, 2010Assignee: Korea Advanced Institute of Science and TechnologyInventors: Sang Yup Lee, Hee Tae Jung, Dae Hwan Jung, Young Koan Ko, Do Hyun Kim, Seok Jae Lee, Byung Hun Kim, Jae Shin Lee
