METHOD OF DETECTING PROTEIN AND DETECTION DEVICE

摘要

A protein detection device and method. The device has a main channel in which is attached either a polar rail molecule or a biomolecular motor which moves on the rail molecule in a direction corresponding to the polarity of the rail molecule. A sub-channel crosses the main channel for receiving a sample including tau-protein. The method includes feeding the sample to the device and detecting a ratio of mutated tau-protein included in the sample, based on motion of the biomolecular motor on the rail molecule or on motion of the rail molecule moved by action of the biomolecular motor.
