WebOct 22, 2024 · Deoxyribonuclease I (DNAse I) is the most abundant nuclease in human blood plasma. It is a non-restriction endonuclease that cleaves phosphodiester linkages within polynucleotide chains to release shorter oligonucleotides [9,10,11,12].DNAse I functions as a waste-management nuclease through degradation of circulating DNA released into … WebApr 10, 2024 · We herein devise a simple and label-free strategy to determine S1 nuclease activity by exploiting the target-induced inhibition of exponential strand displacement amplification (eSDA). In principle, a DNA probe that is designed to produce a large amount of duplexes through a process of eSDA, is degraded by the catalytic activity of S1 nuclease.
