Vitamin B9, commonly known as Folic Acid (FA) or folate in its natural form, is a cornerstone of human and animal health. As an essential coenzyme in one-carbon metabolism, it is indispensable for DNA synthesis, cell division, amino acid metabolism, and proper neurological function. Deficiency is a significant global concern, linked to neural tube defects in newborns, megaloblastic anemia, elevated homocysteine (a cardiovascular risk factor), and impaired immune function. Accurate quantification of Vitamin B9 levels is therefore vital in clinical diagnostics, nutritional research, and quality control across the food, feed, and pharmaceutical industries.
The iElisa Vitamin B9 (Folic Acid) Detection Kit provides a highly sensitive, specific, and robust solution for the quantitative analysis of FA/VB9 in diverse samples. Designed for researchers and quality control professionals, this kit transforms complex biochemical analysis into a reliable, streamlined process, delivering accurate and reproducible results you can trust.
Utilizing an advanced competitive Enzyme-Linked Immunosorbent Assay (ELISA) format, the kit features a highly specific antibody that ensures minimal cross-reactivity. The assay is optimized for high throughput, allowing for the simultaneous analysis of multiple samples with consistent precision.
Key performance specifications are summarized below:
| Feature | Specification | Benefit to Your Work |
|---|---|---|
| High Sensitivity | Low detection limit (typically < 0.5 nmol/L). | Accurately measures low physiological and sub-clinical levels, crucial for deficiency studies. |
| Wide Dynamic Range | Broad quantitative range (e.g., 0.5-50 nmol/L). | Eliminates the need for sample re-dilution, accommodating a wide variety of sample concentrations. |
| Exceptional Precision | Intra- and inter-assay CV < 10%. | Delivers reliable, reproducible data for confident analysis and reporting. |
| Proven Accuracy | Excellent recovery rates (90-110%) in spiked samples. | Ensures measured values reflect true concentrations in complex matrices. |
| Sample Flexibility | Validated for serum, plasma, food extracts, fortified products, and animal feed. | A versatile tool for cross-sector applications, from clinical research to quality assurance. |
Clinical & Nutritional Research: Essential for studies on folate status, pregnancy outcomes, cardiovascular health (homocysteine metabolism), and chronic disease prevention.
Food & Fortification QC: Precisely monitor and verify folic acid content in fortified staple foods (e.g., flour, cereals), infant formula, and dietary supplements to ensure label claim compliance and regulatory standards (e.g., WHO, FDA).
Animal Health & Feed Analysis: Optimize feed formulations by accurately assessing folate content to support livestock growth, reproduction, and overall health.
Pharmaceutical Testing: Verify the active ingredient content in pharmaceutical preparations and raw materials.
