Web2 nov. 2024 · With this starting material, we started our study by testing HRP on pure 2 at pH 7 and 8, with and without cosolvent, to ensure substrate solubilisation [34,37,38]. The use of a cosolvent miscible with water was likely to modify the conformation of the enzyme, and therefore aspects of its activity, such as how it accommodated substrates. WebThe enzyme horseradish peroxidase ( (HRP, Cat No. 11025) is commonly conjugated to secondary antibodies or streptavidin, and used in either indirect or sandwich ELISA assays. The widespread adoption of HRP as a reporter in ELISA is primarly due to three factors.
