Abstract: The present invention has an objective of obtaining more accurate data of microarray experiments by correcting an inter-pin spotting amount error caused upon microarray production using a plurality of pins. Upon microarray production, samples are immobilized on a microarray support using all pins as controls for correcting the inter-pin spotting amount errors. After the microarray experiments, luminescent intensities of the samples used as control spots for correcting the inter-pin spotting amount errors are measured and used to obtain correction parameters for the inter-pin spotting amount errors of respective pins. These parameters are used to correct luminescent intensities of other samples.

Abstract: A method for displaying microarray information by which unknown but useful information is extracted from a mass amount of sample information obtained with microarrays. Luminescent intensity information of sample spots obtained with the microarrays is standardized for each microarray and displayed as a graph as a difference from the standardized luminescent intensity of a sample spot of interest. Accordingly, information can be compared without being influenced by a difference of experiment status between the microarrays or a difference of physical properties between the samples. A three-dimensional graph is displayed by sorting the set of samples and the set of microarrays to which the sample spots belong, under predetermined conditions, and assigning the set of sorted samples and the set of sorted microarrays to X-axis and Y-axis, and the accumulated luminescence intensity to Z-axis.

Abstract: Where a DNA chip corresponding to a bacterium that is a subsequently added identification object is produced, temporal and pecuniary cost is reduced, and even where a probe unique to the DNA sequence of an identification object cannot be designed, precision in identifying DNA comprised in a sample is maximized. First, on designing a probe, a plurality of different probes are prepared to one kind of bacterium. Where some probes come to be not available by addition of bacteria that are new identification objects, identification is carried out using the remaining probes. Where a probe unique to an identification target bacterium cannot be designed, a probability of correct identification is increased by using multiple probes. Moreover, in consideration with a possibility that multiple kinds of bacteria simultaneously exist, a combination of probes that maximizes a probability of correct identification is selected.

Abstract: For comparatively displaying the abundances of a large number of biopolymer species as measured in two different samples in an efficient and distinguishable manner, the values measured for biopolymer abundances in the two samples are normalized so that the sum totals of the measured values as calculated for both samples become equal to each other and the biopolymer abundance ratios between both samples are displayed in the form of a line graph, with the ordinate (logarithmic scale axis) denoting the abundance ratio for each biopolymer between both samples and the abscissa denoting the biopolymer species. On the same graph, the sum of abundances of each biopolymer in both samples may also be displayed along the Y axis as a second axis.

If an expression intensity Ep(I) of a probe P(I), which hybridizes with a sample sm(X) as a search condition, that is, an expression intensity Ep(I)t of an objective probe P(I)t, is set and inputted for a desired sample sm(X) that a user wishes to search by an input/output apparatus 10, an arithmetic unit 20 finds out a microarray A(K) satisfying the search conditions based on a record of experimental results accumulated in a data set file apparatus and displays search results on the input/output apparatus 10.

Abstract: A method of comparing dendrograms created by different references or algorithms displays individual dendrograms (201, 202) on a screen in an overlapped yet distinguishable manner. The overlapped portions of the dendrograms are displaced vertically or horizontally from one another and indicated by different colors for individual dendrograms. A specified branch and elements hanging therefrom can be highlighted when displayed, such that differences in the manner in which individual elements of the overlapped dendrograms are clustered can be easily recognized.

Abstract: A method of conducting accurate identification of biological species with a biochip, and a method of effectuating identification of biological species at a level higher than species are provided. Selection of specific probes for multiple biological species is also facilitated. A plurality of partial sequences A, A′; B, B′; and so on, which are specific to respective targets, are selected as probes in a manner that the partial sequences do not overlap one another. In addition, DNA regions I, J, K and L, which are common to some targets, respectively, are also selected as probes. Alternatively, if there is a common base sequence at leaves below a certain node based on a dendrogram of targets, such a base sequence is designed as a probe unique to the node.

Abstract: Disclosed is a technology capable of acquiring transverse knowledge beyond specialized fields such as medicine and biology. From a knowledge database for accumulating objects as object values, the objects having phrases including terms used in a medical field and/or a biological field, and accumulating relations between the objects, the relations having values, as relation values, for expressing mutual relations between the objects quantitatively, objects related to a query object are extracted based on the relations between the objects, and the query object and the objects extracted are displayed together with the relations there between.

Abstract: A method for displaying results of hybridization experiments using a biochip is provided. In the method, a plurality of control spots spotted in each of a plurality of sections defined on a biochip is measured. The measured data are plotted on a graph for each section, and all of the graphs are simultaneously displayed on a single screen in the same arrangement as that of the sections on the biochip. By simultaneously displaying all of the graphs on a single screen, it is possible to skim the whole biochip to find experimental errors. Also, experimental errors can be quantified with respect to the dispersion of control data on the basis of the linearity of the data points and slope angles defined for each data points on a graph.
