Objectives

  1. Monitor the kinetics and yield of horseradish peroxidase catalyzed oxidation of luminol
    1. Measure UV-Vis absorbance of luminol, HRP, and Luminol+HRP+H2O2
    2. Monitor chemiluminscence of luminol oxidation using stop-flow techniques
    3. Measure kinetics of reaction using stop-flow techniques and absorbance


UV-vis

Stock solutions prepared before class:

  1. Luminol: 13.5mg luminol in 300μL DMSO added to 50mL 5mM Tris pH=8
  2. Buffer: 5mM Tris pH=8
  3. HRP: 1.7μM HRP in 50mL 5mM Tris pH=8
  • Performed 20% dilution of 13.5mg luminol in 300μL DMSO added to 50mL 5mM Tris pH=8. (The luminol stock solution).
    • Make a 10mL stock solution of 20% dilute luminol stock solution.
