Abstract
A chemical substance sensor comprises a microplate including a plurality of holes storing reaction solutions, an air introducer, a light source, a first wavelength selector, a second wavelength selector, a fluorescence detector and a data processor. The reaction solutions contain bovine derivation odorant binding protein. The air introducer introduces air containing odorants into the reaction solutions. Thus, the odorant binding protein contained in the reaction solutions is bonded with the odorants. The odorants in the air are detected by detecting fluorescence obtained when irradiating the odorant binding protein bonded with the odorants with light.
Claims14
A chemical substance sensor characterized by detecting a substance bonded to odorant binding protein.
A chemical substance sensor comprising:
- a storage that stores odorant binding protein having a dimer structure;
- a sample introducer for introducing a sample into the odorant binding protein stored in said storage;
- a light source that irradiates said odorant binding protein in said storage with excitation light;
- a fluorescence detector that detects fluorescence obtained from said odorant binding protein;
- and
- a data processor that processes data related to the intensity of the fluorescence detected by said fluorescence detector.
A method of detecting a chemical substance for detecting a substance bonded to odorant binding protein.
A method of detecting a chemical substance comprising steps of:
- bringing a sample into contact with odorant binding protein having a dimer structure;
- irradiating said odorant binding protein brought into contact with said sample with excitation light for obtaining fluorescence from said odorant binding protein;
- detecting the fluorescence obtained from said odorant binding protein;
- and
- analyzing a chemical substance contained in said sample on the basis of the intensity of said detected fluorescence.
