摘要： It is an object to improve the reliability and accuracy of normalization of gene expression levels, which have been measured separately, by providing a method for the acquisition of an index of high reliability and high accuracy as an index for performing the normalization such that the gene expression levels can be compared and verified. Provided is a method for normalizing a gene expression level, which has been measured for an analysis of a gene expression, by using plural gene expression levels measured for an acquisition of an index. The method includes acquiring a correlation among the plural gene expression levels measured for the acquisition of the index, and using the thus-acquired correlation as an index for normalizing the gene expression level measured for the analysis of the gene expression. The correlation function can be obtained by using, as function values, correlations among plural gene expression levels under at least two sets of experimental conditions (numerals 34 to 38), respectively, with respect to the plural gene expression levels gn acquired under the at least two sets of experimental conditions from cells 31 collected under the at least two sets of experimental conditions, respectively, and selecting a combination of plural ones of the function values such that the plural function values each approximates to a constant value.

摘要： The present invention aims at presenting novel means for analyzing and correcting gene expression amounts. There is provided a gene expression amount normalizing method in which the number of cells in a sample is obtained by measuring a repeated sequence present in a substantially fixed proportion in a genome contained in the sample, and the number of cells obtained is used as an index for normalizing gene expression amounts obtained from the same sample. For example, a DNA sample 33 and an RNA sample 34 are obtained from the same sample 32, the DNA sample 33 is used as a sample for obtaining the number of cells, and the RNA sample 34 is used as a sample for obtaining the gene expression amounts, whereby the number of cells contained in the sample 32 and the gene expression amounts relating to the same sample 32 can be obtained. Therefore, by converting the gene expression amounts to values per a fixed number of cells, the gene expression amounts can be normalized to values which can be compared with those obtained by other gene expression analyses.
