制造商:FUJIFILM Wako Pure Chemical Corporation

儲存條件:冷藏(冷藏運輸)

CAS RN?54576-84-0



◆概況

核酸酶P1分解RNA和熱變性DNA的3'-5'-磷酸二酯鍵。另外,核酸酶P1還分解單核寡核苷酸的3'-磷酸單酯鍵。如果的氯化鈉(pH 6.0)含量超過400mmol/L,它不作用于雙鏈DNA。

◆應用實例

A.

Sample : 200 μL of RNA or heat-denatured DNA at a density of 2 mg/mL.

B.

Reaction Buffer : 200 μL of 0.01 mol/L barbital(veronal) acetate buffer, pH 5.3*.

C.

Enzyme : 100 μL of 100 units/mL of Nucelase P1 solution with distilled water.

D.

top Solution : 500 μL of cold uranyl acetate buffer (0.25% of uranyl acetate and 2.5% perchloric acid)

*barbital (veronal) acetate buffer, pH 5.3: Prepare 0.01 mol/L Barbital Sodium Salt in water and adjust it to pH 5.3 with acetic acid.

1. Mix each 200 μL of A, B and C.

2. Incubate it at 50 degree C for 1 hour.

3. The reaction can be stopped by adding 500 μL of D.
