More Details

Peroxide (e.g. hydrogen peroxide H2O2) is one of the key reactive oxygen species formed under oxidative stress conditions. High levels of peroxide formation have been linked to pathological conditions such as ageing, asthma, diabetes, atherosclerosis, cataract, inflammatory arthritis and neurodegenerative diseases. Simple, direct and automation-ready procedures for quantitative determination of peroxide find wide applications in research and drug discovery. BioAssay Systems peroxide assay kit is designed to measure peroxide concentration in biological samples without any pretreatment. The improved method utilizes the chromogenic Fe3+-xylenol orange reaction, in which a purple complex is formed when Fe2+ provided in the reagent is oxidized to Fe3+ by peroxides present in the sample. The intensity of the color, measured at 540-610nm, is an accurate measure of the peroxide level in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.

How can I measure peroxides in cell cultures?

1. Collect cells by centrifugation 1,000 g for 10 min at 4°C. For adherent cells, use a rubber policeman to harvest cells.

Homogenize or sonicate cell pellet in 1-2 mL of cold buffer containing 0.9% sodium chloride and 5 mM potassium phosphate, pH 7.4.

3. Centrifuge at 10,000 x g for 10 min at 4°C.

4. Use the clear supernatant for assay. If not assaying on the same day, freeze the sample at -80°C and use it within one month.

We want to determine hydrogen peroxide in a sample that likely contains other ingredients such as surfactant, protein, propylene glycol, phosphonic acid, Tween 20, all at 1% or lower. Hydrogen peroxide is probably present at around 1%. Is this assay kit suitable?

Yes, you need to dilute your sample 1,000 to 10,000-fold in water, so that the hydrogen peroxide concentration falls within the detection range of the assay (between 10 and 100 μM). This dilution would eliminate potential interference by other ingredients such as Tween-20.

I have archived some supernatant samples from macrophages that were stimulated for 24hrs with various different stimulants. Am I right in assuming that this kit has no requirement for cells to be functional and that levels of peroxide may loiter in supernatant samples for long enough so that they can be readily measured at 24hrs?

The peroxide assay kit does not require functional cells and peroxide levels can be measured in culture media. We do not know how stable peroxide is in cell culture media and this will likely depend on the cell type and culture conditions. In general, peroxide in serum and urine samples can be detected for several days, even after freezing, but levels may change over time.

My Samples contain sodium pyruvate, is there any way I could use them with this assay?

Sodium Pyruvate below concentrations of 1 mM does not interfere with the assay, if your samples fall in this range you may simply run them. If the sodium pyruvate concentration is between 1 mM and 5 mM, you will need to run the assay with a standard curve made in the media or buffer that contains the sodium pyruvate. The assay will not have as great of detection sensitivity, but will still function. If the sodium pyruvate concentration is greater than 5 mM, the samples will not work. You will need to dilute the samples for them to work.
