Web1 okt. 2024 · Among such enzymes, horseradish peroxidase (HRP) is one of the most popular enzymes, as an HRP-based enzymatic reaction exhibits a high turnover number (kcat) and good long-term stability ( Barbosa et al., 2015; Kang et al., 2009; Xianyu et al., 2015; Yin et al., 2015 ). WebAbstract The use of 3,3′,5,5′-tetramethylbenzidine (TMB) as an electrochemical substrate for horseradish peroxidase (HRP) was investigated. HRP activity has been detected using flow injection analysis at a glassy carbon working electrode polarised at +100 mV versus Ag/AgCl in 0.1 mol l –1 citrate–phosphate buffer (pH 5.0).
