WebJan 1, 2024 · Considering catalytic activity, this DNAzyme mimics horseradish peroxidase, the enzyme most commonly used for signal generation in bioassays. Because DNAzymes exhibit many advantages over protein enzymes (thermal stability, easy and cheap synthesis and purification) they can successfully replace HRP in bioanalytical applications. WebNov 16, 2024 · Artificial enzymes, such as horseradish peroxidase (HRP)-mimicking hemin G-quadruplex DNAzymes, are attracting much attention from researchers in the CL … WebA horseradish peroxidase (HRP)-mimicking DNAzyme sequence is first blocked by the triplex-based molecular beacon (tMB). Upon hybridization with single-stranded DNA inputs, triplex–helix molecular switch occurs, and the released product strand self-assembles into the hemin/G-quadruplex-HRP-mimicking DNAzyme that biocatalyzes the formation of a … preço software hotelaria
