Vitamin D, 25-Hydroxy
Vitamin D, 25-Hydroxy is a high-purity reference standard used for pharmaceutical, clinical, and laboratory testing. It represents the main circulating form of vitamin D in the blood and is essential for calibrating assays that measure vitamin D status in patients.
Typical uses include method development, quality control, and assay validation in laboratories performing vitamin D testing. The material is supplied in a stabilized, accurately weighed form to ensure reliable results across multiple analytical runs.
Key features:
- High purity and certified accuracy
- Stabilized for long-term storage
- Suitable for LC-MS, immunoassay, and GC techniques
- Traceability to recognized reference standards
Recommended applications include:
- Calibration of vitamin D, 25-hydroxy assays
- Quality control materials for clinical laboratories
- Method comparison and validation studies
Storage and handling guidance:
- Store in a cool, dry place away from direct light
- Keep container tightly closed when not in use
- Avoid exposure to moisture and high temperatures
Safety and handling: Handle according to standard laboratory safety practices. Avoid inhalation, ingestion, and contact with skin and eyes. Refer to the material safety data sheet for detailed information.
