POLYNUCLEOTIDES THAT PROMOTE EXPRESSION OF TARGET GENES AMPLIFIED IN MAMMALIAN CELLS

摘要

PROBLEM TO BE SOLVED: To provide means for promoting expression of target genes amplified in mammalian cells.SOLUTION: The invention utilizes a human genome fragment of 3,271 bps (B-3-31) derived from a region of low gene density located on the short arm 16.1 of human chromosome 2, as an expression-promoting polynucleotide.SELECTED DRAWING: Figure 1
