Copper (Cu2+) Colorimetric Assay Kit (Complexing Method)

Copper (Cu²⁺) is an essential trace element that plays pivotal roles in numerous biological processes across both animal and plant systems. It serves as a critical cofactor for a wide range of enzymes, including cytochrome c oxidase involved in cellular respiration, superoxide dismutase that defends against oxidative stress, and tyrosinase responsible for melanin synthesis and plant lignin formation. Beyond enzymatic functions, Cu²⁺ contributes to the maintenance of cell membrane integrity, regulation of iron metabolism, and support of immune system functionality in animals. In plant physiology, it is indispensable for photosynthetic electron transport, pollen development, and resistance to biotic and abiotic stresses.
Abnormal Cu²⁺ levels in biological samples are closely linked to various physiological and pathological conditions. In animal models and clinical research, elevated serum or tissue Cu²⁺ may be associated with oxidative damage, neurodegenerative disorders, or metabolic imbalances. Conversely, deficiency can lead to impaired growth, reduced enzyme activity, and compromised immune responses. For plant research, monitoring Cu²⁺ concentrations in tissues helps evaluate nutrient uptake efficiency, stress tolerance mechanisms, and the impact of environmental factors on plant health.
Accurate and reliable detection of Cu²⁺ is therefore fundamental to advancing research in fields such as comparative physiology, toxicology, plant nutrition, and disease mechanism studies. Traditional detection methods often suffer from limitations such as complex sample pretreatment, long assay times, poor specificity, or high instrument costs. The Copper (Cu²⁺) Colorimetric Assay Kit (Complexing Method) is developed to address these challenges, providing researchers with a streamlined and sensitive tool to quantify Cu²⁺ levels in biological samples efficiently.
