General Information
Ab-10 Rapid Peroxidase Labeling Kit is rapid (in less than 30 min) and easy preparation kit of peroxidase-labeled antibody (Ab) for 10 μg antibody. Reactive Peroxidase (a component of the kit) has succinimidyl ester groups, that can easily make a covalent bond with an amino group of the target antibody without any activation process. This kit contains all the necessary reagents to prepare a peroxidase-labeled antibody.

Caution After a Reactive Peroxidase is taken out from the seal bag, keep the unused Reactive Peroxidase(s) in the bag, seal tightly and store at -20°C. Store the other components at 0-5°C. |
Kit Contents
Reactive Peroxidase | x 3 |
Reaction Buffer | 100 μl x 1 |
Stop Solution | 100 μl x 1 |
Storage Condition
Store at 0-5 ℃
This kit is stable for 1 year at 0-5℃ before opening.
Required Equipment and Materials
- 20 μl adjustable pippet
- Microtube (for sample preparation)
- Incubator (37°C)
- PBS (Phosphate buffered saline)
Precaution
- Use 0.5-1 mg/ml of antibody solution for labeling. If the antibody concentration is more than 1 mg/ml, please dilute the antibody solution with PBS.
- If the sample solution contains small insoluble materials, centrifuge the solution, and use the supernatant for the labeling.
- The microtubes in this kit contain solutions. Since there is a possibility that the droplets might attach to the inside walls or caps, please spin down to drop them down prior to open.
- Some additives in an antibody solution may interfere with the labeling if the concentration is too high. The maximum compatible concentrations of such additives are indicated in Table 1.

- Containing BSA may result in non-specific signal depending on the antibodies used. Removing BSA prior to the peroxidase labeling is recommended in case high non-specific signal is observed.
Protocol
- Add 0.5-1 mg/ml of the antibody solution to a microtube to be an amount of antibody of 10 μg.
- Add Reaction Buffer to the antibody solution (step 1) and mix by pipetting.
- The volume of Reaction Buffer: one-tenth of the antibody solution (Table 2).
- Add the solution (step 2) to Reactive Peroxidase and mix by pipetting.
- Incubate at 37°C for 10 minutes.
- Add Stop Solution to the solution (step 4) and mix by pipetting.
- The volume of Stop Solution: one-tenth of the antibody solution (Table 2).
- Incubate at room temperature for 10 minutes.
- Apply the sample (step 6) for desired experiments or store at 0-5°C.
- The labeled antibody is stable at 4°C for 2 weeks. For longer storage, add equal volume of glycerol to the sample solution and store at -20°C.

Supplimental Information
Mitochondria immunostaining
- HeLa cells were seeded on a μ-slide 8 well (ibidi) and cultured overnight at 37 ℃ in a 5% CO2 incubator.
- The cells were washed using PBS three times, and 4% paraformaldehyde in PBS was added to the μ-slide.
- The cells were then incubated at room temperature for 1 hour.
- The supernatant was discarded and 1% Triton-X in PBS was added to the μ-slide.
- The μ-slide was incubated at room temperature for 30 minutes.
- Once the cells were washed with PBS three times, a blocking solution prepared with PBS was added to the μ-slide.
- The cells were then incubated at 0-5℃ for 1 hour.
- Peroxidase conjugated anti-mitochondria antibody was diluted 50 times with the blocking solution.
- Anti-mitochondria antibody was purchased from Abcam (Product Code: ab3298).
- The supernatant was discarded and the solution (step 8) was added to the μ-slide.
- The μ-slide was incubated at 0-5℃ overnight.
- The cells were washed using Tris buffer (TB, 50 mmol/l, pH 7.5) three times.
- The supernatant was discarded and DAB solution [0.2 mg/ml DAB (Dojindo Laboratories, Product Code:D006), 0.003% H2O2, 50 mmol/l Tris (pH 7.5)] was added to the μ-slide.
- The μ-slide was incubated at room temperature for 10 minutes.
- After the cells were washed using TB three times, TB was added to the μ-slide.
- The cells were observed under a microscope.
