Title: Innovations of Hidehiko Fujii in Base Sequencing Technology
Introduction
Hidehiko Fujii is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of biotechnology, particularly in the development of base sequencing apparatuses. With a total of 4 patents to his name, Fujii's work has advanced the capabilities of genetic analysis.
Latest Patents
Fujii's latest patents include an innovative on-line base sequencing apparatus. This apparatus is equipped with electrophoresis tubes that feature a sheath flow part at each lower end. A sulfuric acid solution with a pH of 1.0 is continuously fed to create a sheath flow. The lower ends of the tubes are irradiated with light close to 260 nm to detect fluorescence components. Each electrophoresis tube is also fitted with a detection system that utilizes an interference filter to select fluorescence components in the range of 340 to 390 nm. The outputs from these detection systems are successively identified to determine base sequences.
Another notable patent is an on-line system base sequencing apparatus that evaluates calibration coefficients for time bases of respective electrophoresis lanes. This evaluation is based on the differences between the positions of signals already outputted and the positions of signals originally outputted at regular intervals. By calibrating the time bases of the electrophoresis lanes with these coefficients, the apparatus can accurately sequence bases, even when differences in electrophoresis speed occur.
