CAS # 32222-06-3
Synonym: 1a, 25-Dihyroxycholecalciferol; Calcitriol  ,

Physical Appearance: Ethanol solution (50 mg/ 50 ml) 1mg-lyophilized solid

Description: Protect from light. Evaporative loss of solvent may occur during storage and handling of the product supplied in ethanol ( 50mg size). If necessary, exact concentration may be redetermined spectrophotometrically in ethanol solution (lmax = 264 nm; e = 19,000 M-1 cm-1; 2.2mg/ml yields A264 = 0.10).

A central regulator of bone and calcium homeostasis and the active hormonal form of vitamin D1. Acts via binding to an intracellular receptor/transcription factor (KD = ~0.6 nM2). Inhibits proliferation and induces differentiation in a variety of cells3-5. Directly activates protein kinase C at physiological concentrations (EC50 = 16 nM)6.

Solubility: Soluble in DMSO,ethanol, acetone, alcohol, methylene chloride, methanol, ehtyl acetate, THF l max = 265 nm (ethanol). Store solutions at -20oC for up to 3 months.
