产品说明
应用
- 从体外翻译系统中去除内源性RNA
- RNA测序实验
核酸酶S7已用于核糖体分析的核糖核酸酶选择过程研究。
生化/生理作用
Nuclease S7 is an endonuclease that mainly cleaves single-stranded substrates. It also cleaves double-stranded DNA or RNA. It cleaves the 5′-phosphodiester bonds of RNA and DNA to yield 3′-mononucleotides and oligonucleotides. Activity of the enzyme is dependent on Ca2+ and can be completely inactivated by the addition of EDTA. Nuclease S7 cleavage is highly specific to AT rich region than GC on the DNA.
单位定义
一单位酶释放的足够量的酸溶性寡核苷酸可使A260增加1.0。
储存及稳定性
未开封试剂储存于2-8 ℃；1 mg/mL的稀释液则储存于-15 to -25 ℃。
其他说明
仅用于生命科学研究。不可用于诊断。
