    　View Summary

    A chemically cross-linked DNA gel in acetone-water mixtures involving salt is demonstrated to bring about the volume phase transition with varying the salt concentration. The salt concentration at the discrete volume change depends strongly on the valency of the positive salt ion in the solution. The transition salt comcentration for NaCl is several hundred times larger than the transition MgCl_2 concentration. For NaCl, the first order phase transition is observed at the NaCl concentration of 4 × 10^<-2> mol/l for the 60% acetone-water mixtures. For MgCl_2, the discrete volume change are observed at 8 × 10^<-5> mol/l of MgCl_2 concentration for 50% acetone-ware mixtures, 7 × 10^<-5>mol/l for 60%, respectively. （管理者追加）リポジトリ登録情報を移行しました。確認のうえ、加除修正をしてください。
