特點
DNase I脫氧核糖核酸酶 | Deoxyribonuclease I, DNase I 貨號 abx082222
DNase I (脫氧核糖核酸酶I, 即Deoxyribonuclease I)(IV 型)是一種從牛胰腺(bovine pancreas)中分離出來的酶。可消化單鏈或雙鏈DNA的脫氧核糖核酸內切酶, 它識別並切割磷酸二酯鍵,產生5′ 端為磷酸基團,3′ 端為羥基的單脫氧核苷酸或單鏈或雙鏈的寡脫氧核苷酸。生物活性≥ 2000 Kunitz 單位/mg 蛋白質在 pH 5.0 和 25 °C 下,使用 I 型或 III 型 DNA 作為底物,一個 Kunitz 單位將產生每分鐘每毫升 0.001的 A 260變化。
