SURFACE FOR DETECTING INTERACTION BETWEEN SUBSTANCES, DNA CHIP, ANOTHER SENSOR CHIP, PROBE AND REDUCTION METHOD OF BACKGROUND NOISE FLUORESCENCE

摘要

PROBLEM TO BE SOLVED: To simplify a series of assay processes reaching detection from interaction and to achieve the enhancement of an S/N ratio by simply and certainly removing fluorescence noise.;SOLUTION: A detection surface is a surface for detecting the interaction between a probe substance (1a) and a target substance (2a) and is equipped with the probe substance (1a), which is labelled with a fluorescent substance (F₁) and keeps the unlabeled terminal fixed to the surface S of a solid phase, and a fluorescence altering substance (Q₁) for suppressing or modulating the emission of the fluorescent substance (F₁). The surface is constituted so as to perform the emission or modulation release of the fluorescent substance (F₁) by the above interaction. A sensor chip equipped with the detection surface, etc. are also provided.;COPYRIGHT: (C)2007,JPO&INPIT
