Description
Total Oxidant Status (TOS) Colorimetric Assay Kit is suitable for detecting the total oxidative status in cell, tissue, and serum samples, as well as other liquid samples.
Detection Principle
Under acidic conditions, oxidative substances in the sample can oxidize Fe2+ to Fe3+, which then forms a blue-purple complex when combined with phenolphthalein. Within a pH range of 2-3, the maximum absorption wavelength is near 590 nm, and the intensity of coloration is directly proportional to the concentration of oxidative substances within a certain concentration and time frame, thereby indirectly determining the total oxidative status of the sample. When detecting tissue or cell samples with this reagent kit, it is necessary to measure the total protein concentration. We recommend using our company's BCA reagent kit for this measurement.
Storage
Store between 2-8°C and protect from light exposure. The product can be stored under these conditions for up to three months.
Notes
- The reagent kit is for research use only. Our company shall not be liable for any issues arising from its use in clinical diagnosis or any other purposes, nor shall it assume any legal responsibility.
- Before conducting experiments, carefully read the instructions and adjust the instruments accordingly. Strictly follow the instructions during the experiment.
- Wear laboratory attire and latex gloves for protection during experiments.
- The detection range of the reagent kit does not necessarily correspond to the concentration range of the analyte in the sample. If the concentration of the analyte in the sample is too high or too low, appropriate dilution or concentration of the sample should be performed.
- If the sample to be tested is not listed in the instruction manual, it is recommended to conduct a preliminary experiment to verify its detection effectiveness.
- The final experimental results are closely related to the effectiveness of the reagent, the actions of the experimenter, and the experimental environment, among other factors. Our company is only responsible for the reagent kit itself and is not liable for sample consumption resulting from its use. Before use, please consider the potential usage volume of the sample and reserve an adequate amount.
