AT A GLANCE
- Prepare ELISA plate
- Prepare peroxidase working solution
- Add 100 µL/well of peroxidase working solution into the ELISA plate
- Incubate at room temperature for 15 - 60 minutes
- Monitor fluorescence intensity at Ex/Em = 540/590 nm
Thaw all the kit components at room temperature before starting the experiment.
PREPARATION OF STOCK SOLUTION
1. Amplite™ Red Peroxidase Substrate stock solution (200X):
Add 250 µL of DMSO (Component D) into the vial of Amplite™ Red Peroxidase Substrate (Component A). Note: 50 µL of the Amplite™ Red peroxidase substrate stock solution is enough for 1 plate.
2. H2O2 stock solution (20 mM):
Add 22.7 µL of 3% H2O2 (0.88 M, Component B) into 977 µL of Assay Buffer (Component C). Note: The diluted H2O2 stock solution is not stable. The unused portion should be discarded.
PREPARATION OF STANDARD SOLUTION
For convenience, use the Serial Dilution Planner: https://www.aatbio.com/tools/serial-dilution/11540
Mouse IgG (not included) can be used to generate a standard curve. Dilute total mouse IgG with 0.2 M sodium bicarbonate buffer (pH 9.4) into microplate, using an initial concentration of 3 ug/mL and 1:3 dilution factor.
PREPARATION OF WORKING SOLUTION
1. Goat anti-mouse IgG-HRP conjugate working solution:
Add 2 µL of goat anti-mouse IgG-HRP conjugate (Component E) to 10 mL of PBS with 1% BSA (PBS-BSA, not included). Note: 10 mL of goat anti-mouse IgG-HRP conjugate working solution is enough for 1 plate. The concentration of this goat anti-mouse IgG-HRP conjugate working solution is recommended as an initial concentration to try. The optimal concentration for each particular application should be determined empirically.
2. Peroxidase working solution:
Add 50 μL of Amplite™ Red Peroxidase Substrate stock solution (200X) and 100 μL of H2O2 stock solution (20 mM) into 9.85 mL of Assay Buffer (Component C) to make a total volume of 10 mL Peroxidase working solution. Keep from light.
SAMPLE EXPERIMENTAL PROTOCOL
Prepare ELISA plate:
- Perform all necessary ELISA preparation steps.
- Wash the ELISA wells three times with PBS containing 0.02% to 0.05% Tween® 20 (PBS-Tween) and drain.
- Add 100 µL of prepared goat anti-mouse IgG-HRP conjugate working solution into each well.
- Incubate at room temperature for 30 minutes. Drain off the HRP conjugate.
- Wash the wells three times with PBS-Tween and drain.
Run peroxidase assay in ELISA plate:
- Add 100 µL of peroxidase working solution into each drained microplate well containing the samples and controls.
- Incubate the reaction at room temperature for 30 minutes or longer, protected from light.
- Monitor the fluorescence increase with a fluorescence plate reader at excitation 530 - 570 nm (optimal at 540 nm) and emission 590 - 600 nm. Note: The plate can also be read by an absorbance microplate reader at the wavelength of 576 ± 5 nm. However, the absorption detection has lower sensitivity compared to fluorescence reading.
