Abstract
Technology is disclosed for highly accurate automated execution of processing for alignment of a detection area to a DNA microarray image file and processing for quantitative determination of success/failure of the alignment during DNA microarray analysis. A probe reactive chip used for the technology comprises a substrate; a spot region wherein spots for fixing a probe capable of specifically reacting to a sample marked so as to be optically detectable are formed in a matrix on a surface of the substrate; and a reference pattern area, which is arranged within the spot region or approximate to the spot region, and comprises a plurality of different alignment marks in order to correct misalignment of the spot during analysis of the sample on the surface of the substrate.
