Control Plasma
Control Plasma is a standardized plasma preparation used for quality control and calibration in clinical assays, diagnostic tests, and research applications. It ensures the accuracy and reliability of test results by providing known quantities of analytes and mimicking the biological matrix of patient samples.
Key Components
- Plasma Matrix: Derived from human or animal blood, containing a range of proteins, lipids, and other components to simulate natural plasma.
- Stabilizers: Added to maintain the integrity of the plasma and prevent degradation or alteration of its components over time.
- Analyte Concentrations: Contains known concentrations of specific analytes (e.g., coagulation factors, lipids, hormones) for calibration and validation purposes.
Technical Specifications
- Volume: Typically provided in vials or tubes, with volumes ranging from 1 mL to 10 mL or more, depending on application needs.
- Concentration: Analyte concentrations are precisely quantified and provided with a certificate of analysis.
- Storage Conditions: Usually stored at -20°C or -80°C for long-term preservation. Thawing should be done according to manufacturer’s instructions to maintain stability.
Applications
- Quality Control: Used to verify the performance of assays, ensuring that they are functioning within established parameters.
- Calibration: Serves as a reference for calibrating analytical instruments and methods.
- Validation: Aids in validating new assay methods and ensuring consistency across different test runs.
Usage Instructions
- Preparation: Thaw the plasma according to the manufacturer’s recommendations. Mix gently to ensure uniform distribution of analytes.
- Handling: Use aseptic techniques to avoid contamination. Use the plasma within the specified time frame after thawing.
- Compatibility: Ensure compatibility with assay reagents and systems to avoid interference with test results.
Quality Control
- Certification: Each batch is tested for analyte levels, purity, and stability. A certificate of analysis is provided.
- Performance: Regular performance checks are conducted to ensure consistent quality and reliability.
