DNase I (RNase-free) DNase I 无 RNase Deoxyribonuclease I 脱氧核糖核酸酶I 替代 NEB M0303S NEB M0303L Promega Z3585 Thermo EN0521, GMP grade
DNase I digests DNA efficiently
Fig.1 Add 1 μg DNA and different activity units of DNaseI in a total reaction volume of 10 μl. Compared with competitor 1 and 2, DNase I of kactus has a stronger digestive effect.
Product Description
DNase I, (RNase-free) is an endonuclease that nonspecifically cleaves DNA to release di-, tri- and oligonucleotide products with 5´-phosphorylated and 3´-hydroxylated ends (1,2). DNase I acts on single- and double-stranded DNA, chromatin and RNA:DNA hybrids.
