NUCLEIC ACID DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce a false positive in genetic screening by finding out the generating factor of a nonspecific signal (nonspecific hybridization) which is a problem in a detection method using nucleic acid chromatography.SOLUTION: A development and detection (hybridization) step of a test solution in nucleic acid chromatography is performed under the condition that an air flow between a solid-phase carrier and outside environment is interfered and air tightness of the surface of the solid-phase carrier is maintained.
