用于从蛋白质样品中除去 DNA。 Deoxyribonuclease I from bovine pancreas has been used in a study to investigate a two-dimensional zymogram analysis of nucleases in Bacillus subtilis. Deoxyribonuclease I from bovine pancreas has also been used in a study to investigate the effects of minor and major groove-binding drμgs and intercalators on the DNA association of minor groove-binding proteins RecA and deoxyribonuclease I. Bovine pancreatic deoxyribonuclease is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding polynucleotides with free hydroxyl group at the 3 position and phosphate group at the 5 position. The average chain length of a limit digest is a tetranucleotide.

The average chain length of a limit digest is a tetranucleotide. Used for the removal of DNA from protein samples. Deoxyribonuclease I from bovine pancreas has been used in a study to compare several procedures for reducing RNase contamination in preparations of DNase. Deoxyribonuclease I from bovine pancreas has also been used in a study to investigate the effect of the composition of sodium dodecyl sulfate preparations on the renaturation of enzymes after polyacrylamide gel electrophoresis.
产品名称 DNA酶I 来源于牛胰腺(重组) 产品名称 Deoxyribonuclease I from bovine pancreas(Recombinant) 别名脱氧核糖核酸酶 I 英文别名 Deoxyribonucleate 5′-oligonucleotido-hydrolase;DNase I CAS编号 9003-98-9 分子式 PubChem CID 597667 MDL号 MFCD00130918 EC号 232-667-0 规格或纯度 ≥5000 units/mg protein 备注卖完停产，不再备货 生化机理 DNase I is an endonuclease that acts on phosphodiester bonds adjacent to pyrimidines to produce polynucleotides with terminal 5′-phosphates. In the presence of Mg2+, DNAse I cleaves each strand of DNA independently and the cleavage sites are random. Both DNA strands are cleaved at approximately the same site in the presence of Mn2+. Divalent cations such as Mn2+, Ca2+, Co2+, and Zn2+ are activators of the enzyme. A concentration of 5 mM Ca2+ stabilizes the enzyme against proteolytic digestion. The pH optimum is found to be between 7 and 8. DNAse I from bovine pancreas consists of four chromatographically distinguishable components, A, B, C, and D, with their molar ratios being 4:1:1 respectively. Only minor amounts of D are found. 2-Mercaptoethanol, chelators, sodium dodecyl sulfate (SDS)6 and actin7 are known to inhibit the enzyme activity. 敏感性易潮湿 储存温度 2-8°C储存 运输条件冰袋运输 品牌阿拉丁
