DNase I is an essential endonuclease enzyme used in laboratories and clinical settings for RNA purification. It efficiently hydrolyzes the phosphodiester bonds in DNA, including single-stranded and double-stranded DNA, chromatin, and RNA:DNA hybrids, guaranteeing the isolation of RNA samples that are entirely free from DNA contamination. High-quality GMP Grade DNase I is available to meet the rigorous standards required for research, pre-clinical, and clinical applications.
