| Product Name | Two-Step Direct LDL-C Reagent with 15.0 mmol/L Upper Limit |
| Catalog No. | BLTR-0026 |
| Description | Alta DiagnoTech LDL-C reagent uses a selective two-step enzymatic process for direct serum measurement of low-density lipoprotein cholesterol. |
| Intended Use | For in vitro quantitative measurement of low-density lipoprotein cholesterol in human serum. |
| Principle / Technology | In the first reaction, a polyanion complexes LDL and a surfactant prevents it from reacting, while other lipoproteins are enzymatically hydrolyzed and their hydrogen peroxide is consumed without color formation. In the second reaction, another surfactant releases LDL cholesterol for a cholesterol-enzyme Trinder reaction; absorbance is proportional to LDL-C concentration. |
| Detection Method | Two-step direct enzymatic method |
| Sample Type | Human serum |
| Performance Range / Specifications | Linearity upper limit: 15.0 mmol/L. Samples above the limit may be diluted with 0.9% sodium chloride solution and the result multiplied by the dilution factor. |
| Storage Conditions | Store unopened and protected from light at 2-8°C for up to 12 months. After opening, store protected from light at 2-8°C and use within 1 month if uncontaminated. Do not freeze. |
| Shelf Life | 12 months unopened; 1 month after opening when stored uncontaminated at 2-8°C. |
| Package Specifications | Available in 80 mL, 1,000 mL and 10 L formats. |
| Safety | Avoid contact with skin and mucous membranes. Rinse exposed areas with water and seek medical attention if needed. Dispose of waste according to applicable local requirements. |
| Product Type | Biochemical assay reagent kit |
| Abbreviation | LDL-C |
| Usage Precautions | Use as a two-reagent method rather than a single-reagent method. Do not mix different reagent lots; recalibrate when changing lots. Laboratories should verify parameters for other instruments. |
| Analytes / Targets | Low-density lipoprotein cholesterol |
For research use only, not for clinical use.
