● Introduction:
Ribonuclease A (RNase A) is a single chain polypeptide containing 4 disulfide bridges. In contrast to RNase B it is not a glycoprotein. RNase A can be inhibited by alkylation of the histidine-12 or histidine-119 which are present in the active site of the enzyme. Activators of RNase A include potassium and sodium salts. The optimal temperature for activity is60°C, although the enzyme does exhibit activity from 15-70°C. The pH optimum is 7.6, with an activity range of 6-10. The highest activity is exhibited with single stranded RNA. RNase A is a very stable enzyme and can withstand temperatures up to100°C. At100°C, RNase A is most stable between pH 2.0 and 4.5.
● Stability:
RNase A power is recommended to be stored in a freezer location (-20°C). Stock solutions stored in frozen aliquots are stable for at least 6 months.
● 質(zhì)粒提取中RNaseA的使用:
RNaseA在質(zhì)粒中的終濃度推薦為100μg/ml,即在質(zhì)粒溶液中按照1/100體積加入10mg/ml RNaseA即可,如50μl質(zhì)粒中加入0.5μl RNaseA溶液,37℃孵育10分鐘。
