| 摘要 |
The present invention provides a method and/or means for collecting and analyzing an individual cell in a tissue, and at the same time, quantitatively monitoring the expression levels of various genes while keeping two-dimensional information in the tissue. Specifically, the present invention provides a method comprising preparing a cDNA library from mRNA while keeping two-dimensional cellular distribution information and obtaining the gene expression levels at any site or all sites at a level of single cell. More specifically, the present invention provides a method comprising preparing a cDNA library in a sheet-form from mRNA while keeping two-dimensional cellular distribution information and repeatedly using the cDNA library in the detection of the gene expression, thereby allowing measurement of the expression distribution for a number of genes at a high accuracy. |
