    Product Description

    PTZ-343 is a water-soluble enhancer of luminol (Item No. 16803) chemiluminescent peroxidation catalyzed by horseradish peroxidase (HRP).1 It acts as an electron transfer mediator, reacting with HRP-II to release HRP and a PTZ-343 radical, which oxidizes luminol anions to induce light emission. HRP-induced chemiluminescent light emission increases by >800% in the presence of PTZ-343. It also enhances soybean peroxidase-induced chemiluminescence, increasing sensitivity and lowering the detection limit from 1.1 to 0.18 pM.2

    WARNING This product is not for human or veterinary use.
