Beschreibung
Calcifediol monohydrate (25-hydroxyvitamin D3 monohydrate) is a potent VDR ligand and vitamin D supplement. Calcifediol is a precursor of the Vitamin D Endocrine System (VDES), which is hydroxylated in the liver to produce the active form of calcitriol. Calcifediol rapidly raises serum levels of Calcifediol rapidly increases serum levels of vitamin D.
Chemische Eigenschaften
White or almost white crystals.
Verwenden
Calcifediol is a major circulating metabolite of vitamin D3 and acts as a competitive inhibitor with an apparent Ki of 3.9 μM. It is produced in the liver and is the best indicator of the body’s vitamin D stores. It is effective in the treatment of ricket
Allgemeine Beschreibung
A Certified Spiking Solution
? of 25-Hydroxyvitamin D3, a prohormone whose blood serum levels are used to determine Vitamin D nutritional status. This solution standard is suitable for critical quantitative applications in research and clinical environments including: for use in preparation of controls and calibrators for LC/UV and LC-MS/MS assays; as system tuning/suitability standards; linearity verification; internal proficiency testing; and for OEM use in preparation of reagents, development of assays and instrument IQ/OQ. The stable, quantitative solution format provides significant benefits to the user including material savings, increased efficiency of labor, and convenience of use. The shelf stable Snap-N-Spike
? format allows laboratories to eliminate painstaking weighing operations and provides the ability to spike a known concentration of analyte into their matrix of choice just before use.
Sicherheit(Safety)
The European Chemicals Agency (ECHA)- external site hazard classification and labeling for calcifediol monohydrate is 'Danger! According to the classification provided by companies to ECHA in CLP notifications, this substance is fatal if swallowed, is fatal in contact with skin, is fatal if inhaled, causes damage to organs through prolonged or repeated exposure, is suspected of damaging fertility or the unborn child and may cause long lasting harmful effects to aquatic life'.
Dosage
Calcidiol monohydrate contains the monohydrate form of the major circulating metabolite of vitamin D3 in the body and is a source of 1,25-dihydroxyvitamin D, the biologically active form of vitamin D. Calciferol monohydrate (25-hydroxycholecalciferol monohydrate) is safe under recommended conditions and level of use (up to 10 μg/day) and is safe for children >11 years of age and adults, including pregnant and lactating women.
