Selenium is an essential trace element that plays a critical role in various biological processes, including antioxidant defense, immune function regulation, and thyroid hormone metabolism. Its balanced presence in biological systems is closely linked to cellular health, as it serves as a key component of selenoproteins—enzymes that protect cells from oxidative stress-induced damage.
In research settings, accurate quantification of selenium levels in biological samples is fundamental to understanding its physiological and pathological roles. For instance, studies on nutritional deficiencies, chronic diseases, and environmental exposure often require precise measurements of selenium in serum, plasma, animal tissues, or cell cultures.
Traditional methods for selenium detection, such as atomic absorption spectrometry or inductively coupled plasma mass spectrometry, often involve complex sample preparation, expensive instrumentation, and lengthy analysis times. These limitations create a demand for efficient, user-friendly, and cost-effective assay solutions that can deliver reliable results for research applications.
The Selenium Colorimetric Assay Kit is developed to address this need, providing a streamlined approach for quantitative selenium analysis while maintaining high accuracy and sensitivity—ideal for academic research, pharmaceutical development, and environmental toxicology studies.
Targets inorganic salt ions research, specifically designed for selenium quantification in serum (plasma), animal tissues, and cell samples.
Operates with a microplate reader at a detection wavelength range of 415-425 nm (optimal at 420 nm), compatible with standard laboratory equipment.
Offers a broad detection range of 0.06-16.00 mmol/L, covering the typical selenium concentration ranges in most biological research samples.
Requires a small sample volume (100-150 μL), minimizing sample consumption and preserving valuable research materials.
Completes the entire detection process in just 50 minutes, enabling high-throughput sample analysis and efficient workflow.
Features long-term storage stability (6 months at -20°C, protected from light), ensuring product reliability and reducing repeated purchases.
Available in two flexible sizes (96 T/80 samples and 48 T/32 samples) to accommodate different experimental scales and budget requirements.
Exceptional accuracy with low inter-assay variation (0.5-0.7%) and intra-assay variation (0.3-0.4%), ensuring consistent and trustworthy research data.
High sensitivity with a detection limit of 0.06 mmol/L, capable of detecting low selenium concentrations in samples with trace levels.
No complex sample pretreatment required, simplifying experimental procedures and reducing the risk of human error.
Colorimetric detection method is straightforward to operate, suitable for researchers of all skill levels without specialized technical training.
Cost-effective compared to advanced instrumental methods, providing reliable results without high equipment investment.
Strictly optimized for research use, with formulations tailored to minimize interference from common biological matrices.
For research use only, not for clinical use.
