A composite layer included in an element is formed using the composite as an element material. The composite layer is arranged between a first electrode and a light emitting layer or between a second electrode and a light emitting layer. The composite layer has high conductivity; therefore, drive voltage does not rise even if a film thickness is increased.Type: GrantFiled: November 24, 2005Date of Patent: January 6, 2015Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Ryoji Nomura, Satoshi Seo, Hiroko Abe, Takako Takasu, Hideko Inoue, Hisao Ikeda, Daisuke Kumaki, Junichiro Sakata

Publication number: 20140242606Abstract: The present invention relates to a probe for iFRET and use thereof. Specifically, the present invention relates to a novel probe for iFRET, a method for preparing the probe for iFRET, a method for searching a target protein-specific binding site or a molecule having the binding site using the probe for iFRET, and a method for imaging the target protein using the probe for iFRET. The probe for iFRET according to the present invention utilizes an amino acid in a protein as a fluorescent donor, unlike the conventional FRET method. Therefore, only one fluorescent material is used, and its emission wavelength is distinct from the intrinsic fluorescence of the protein. Thus, high specificity and sensitivity are ensured, and the quantity, activity and mechanism of various proteins can be analyzed in an easy and accurate manner.Type: ApplicationFiled: June 25, 2012Publication date: August 28, 2014Applicant: KOREA RESEARCH INSTITUTE OF BIOSCIENCE AND BIOTECHNOLOGYInventors: Sang Jeon Chung, Ju Hwan Kim, Elena Ruchkina, Hyo Jin Kang
