DNA ELEMENT HAVING ACTIVITY OF ENHANCING FOREIGN GENE EXPRESSION

摘要

PROBLEM TO BE SOLVED: To provide means for stably achieving high expression of a foreign gene in mammalian cells using a novel DNA element.SOLUTION: The present invention provides a DNA element which enhances the activation of transcription by changing the chromatin structure around a gene locus into which a foreign gene expression unit has been introduced.SELECTED DRAWING: None
