A METHOD FOR INDENTIFYING A BIOMOLECULE

摘要

A method for indentifying a biomolecule is provided to indentify each DNA from one sample although various kinds of DNAs are PCR-amplified at the same time by indentifying A and B which are PCR products by utilizing transition temperature property. A biomolecule detecting apparatus having a field effect transistor(FET) is used in order to indentify a biomolecule. A method for indentifying a biomolecule comprises steps of: (a) heating a sample including the biomolecule into a biomolecule detecting apparatus in which the sample is injected; (b) measuring current flowing to a channel formed between a source region and a drain region of the field effect transistor; (c) calculating transition temperature which is temperature when current change amount is maximum from current data measured in the step (b); and (d) indentifying the biomolecule using the transition temperature.
