WebDec 19, 2024 · Abstract. In this work, the chromogenic catalysis of 3,3’,5,5’-tetramethylbenzidine (TMB) with horseradish peroxidase (HRP) in presence of hydrogen peroxide (H 2 O 2), the most widely used chromogenic reaction in enzyme linked immunosorbent assay (ELISA) was deeply studied in the medium containing sodium … WebKinetics studies suggested that the affinity of Cu-MOF to TMB and OPDA is close to that of HRP. Based on the color reaction of TMB with H 2 O 2, colorimetric methods for the detection of H 2 O 2 and glucose were established. Moreover, the detection of ascorbic acid and sodium thiosulfate was also performed upon the inhibition of TMB oxidation.
