Abstract

　本発明は宿主細胞の染色体外で増幅するベクターＤＮＡ、および当該ベクターを用いた目的遺伝子の増幅方法を提供する。本発明にかかるベクターは、真核生物細胞内で機能する哺乳動物複製開始領域、および核マトリックス結合領域を具備するベクターであって、直鎖状であり、かつ少なくとも片側の末端の形状がヘアピン構造であることを特徴としている。本発明のベクターを用いることで、目的遺伝子をＤＭの形態、すなわち染色体外で高度に増幅させることが可能となる。したがって、反復配列依存的な転写抑制を受けることなく、目的遺伝子の増幅コピー数の増加に比例して、目的遺伝子から発現するタンパク質量も増加すると考えられる。
