Substrate for biomolecule microarray, process for producing the same, biomolecule microarray and method of collecting data on biomolecule microarray

摘要

A biomolecular microarray substrate having a spot for fixing a biomolecular probe on a surface thereof. The spot of light-reflecting layer is present between the biomolecular probe-fixing spot and the substrate surface. A method of manufacturing the biomolecular microarray substrate. A biomolecular microarray having a biomolecular probe-fixing spot in which a biomolecular probe is fixed by a biomolecular probe-fixing spot having the biomolecular microarray substrate. A data collection method for biomolecular arrays. Fluorescently labeled target biomolecules is interacted with a biomolecular microarray having, on a substrate surface, biomolecular probe-fixing spots that fix biomolecular probes on light-reflecting layer spots; excitation light is directed onto the biomolecular microarray obtained and reflected light and fluorescence are simultaneously measured from the biomolecular microarray; a biomolecular probe-fixing spot present on a light-reflecting layer spot is specified from differences in the intensity of the light reflecting off of the biomolecular microarray; and fluorescence data are obtained from within the scope of the specified spot. Alternatively, light is directed onto the biomolecular microarray obtained and reflected light is measured from the biomolecular microarray; a biomolecular probe-fixing spot having a light-reflecting layer spot is specified from differences in the intensity of the light reflecting off of the biomolecular microarray; excitation light is directed only onto the scope of the specified biomolecular probe-fixing spot and measuring the fluorescence; and fluorescence data are obtained from the scope of the specified spot.
