Abstract
Serial analysis of gene expression, SAGE, a method for the rapid quantitative and qualitative analysis of transcripts, has been improved to provide more genetic information about each analyzed transcript by use of MmeI restriction endonuclease. In SAGE, defined sequence tags corresponding to expressed genes are isolated and analyzed. Sequencing of over 1,000 defined tags in a short period of time (e.g., hours) reveals a gene expression pattern characteristic of the function of a cell or tissue. Moreover, SAGE is useful as a gene discovery tool for the identification and isolation of novel sequence tags corresponding to novel transcripts and genes.
