== | ==Purpose== | ||
* | * To determine enzymatic activity of horseradish peroxidase via the usage of fluorometer under 510nm. | ||
==Procedure== | |||
* Stock solutions were pre-made 24 hours ago before samples were mixed and run under fluorometer. See [[User:Melissa Novy/Notebook/CHEM-571/2012/09/18|Melissa's Notebook]] for details in making stock solutions on concentration of horseradish peroxidase and 4-Idophenol that's used in solutions. | |||
* Luminol stock solution was diluted to 2.5mM and mixed with carbonate buffer. See [[User:Melissa Novy/Notebook/CHEM-571/2012/09/19|Melissa's Notebook]] for details of the dilution and reasoning behind making the luminol stock. | |||
* Samples were mixed with 4-Idophenol, H2O2, luminol, and horseradish peroxidase, respectively, before measurements were taken. For details in concentration of stocks added, see below table: | |||
* Fluorometer was set to wavelength 510nm. All data were collected for a period of ~300 seconds to make sure samples has reached equilibrium and had completed in fluorescing. | |||
==Notes== | |||
* Fluorescence at 510nm was plotted against time in seconds. Only three samples were run: 1.25mM luminol and 1.7mM H2O2, 625uM luminol and 1.7mM H2O2, and 625uM luminol and 850uM H2O2. Within the samples also added 18mM 4-iodophenol and 2.3uM horseradish peroxidase. | |||
