基本信息
产品描述 | 级别:BR Specific activity:≥20u/mg protein 活力定义:One Unit hydrolyzes one micromole of p-nitrophenyl thymidine-5-phosphate per minute at 25℃, pH 8.9. 产品描述:Venom exonuclease (Phosphodiesterase I) successively hydrolyzes 5'-mononucleotides from 3'-OH-terminated ribo- and deoxyribo-oligonucleotides. The enzyme has an optimal pH range of 9.8-10.4 and a molecular weight of 115 kDa. Phosphodiesterase is inhibited by reducing agents such as glutathione, cysteine and ascorbic acids. It is completely inhibited by 5mM EDTA while ATP, ADP and AMP are partial inhibitors. The enzyme has an absolute requirement for Mg2+ 性状白色或类白色粉末 用途:本品仅供科研,不得用于其它用途。用于序列核酸的研究 保存:-20℃ |
