土壤过氧化氢酶主要分解土壤中的过氧化氢,从而减轻过量累积的过氧化氢对植物根系的危害。本试剂盒提供一种简单、灵敏、快速的测定方法:CAT催化过氧化氢分解为水和氧气,剩余的过氧化氢与高灵敏显色探针反应生成有色产物,该产物在510 nm处有最大吸收峰。通过测定过氧化氢的减少量,即可计算土壤中CAT活性。本试剂盒的显著特点在于将检测波长从紫外区(240 nm,过氧化氢直接检测波长)转换至可见光区(510 nm),无需使用石英比色皿或紫外透射板。此外,过氧化氢本身极不稳定,直接测定易导致读数波动,且蛋白质等组分在紫外区也有光吸收,会影响结果的准确性。
Soil catalase (CAT) mainly decomposes hydrogen peroxide in the soil, thereby alleviating the damage caused by excessive accumulation of hydrogen peroxide to plant roots. This kit provides a simple, sensitive, and rapid assay method: CAT catalyzes the decomposition of hydrogen peroxide into water and oxygen. The remaining hydrogen peroxide reacts with a highly sensitive chromogenic probe to generate a colored product with a maximum absorption peak at 510 nm. By measuring the decrease in hydrogen peroxide, the CAT activity in the soil can be calculated. A notable feature of this kit is that it shifts the detection wavelength from the ultraviolet region (240 nm, the direct detection wavelength for hydrogen peroxide) to the visible light region (510 nm), eliminating the need for quartz cuvettes or UV‑transparent microplates. Moreover, hydrogen peroxide itself is highly unstable, and direct measurement tends to cause reading fluctuations. Additionally, components such as proteins also absorb light in the UV region, which can interfere with the accuracy of the results.
