| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

| Description | Calcitetrol(1α, 24, 25-Trihydroxy VD3) is the hormonally active form of vitamin D with three hydroxyl groups.
IC50 value:
Target: Calcitriol increases blood calcium levels ([Ca2+]) by promoting absorption of dietary calcium from the gastrointestinal tract and increasing renal tubular reabsorption of calcium, thus reducing the loss of calcium in the urine. Calcitriol also stimulates release of calcium from bone by its action on the specific type of bone cells referred to as osteoblasts, causing them to release RANKL, which in turn activates osteoclasts.

Further oxidation of hydroxycalcidiol by calcidiol 24-hydroxylase. A study with the mature enzyme expressed in Escherichia coli.[Pubmed:7925346]
Eur J Biochem. 1994 Sep 1;224(2):335-43.
The coding region of the cDNA for rat kidney calcidiol 24-hydroxylase (P450cc24), which is involved in calcium homeostasis in animals, was inserted into an expression vector pKK223-3. The recombinant plasmid was formed in a specific manner without deletion or substitution of any parts of the coding region of the cDNA. When the resulting plasmid was introduced into Escherichia coli JM109, the recombinant cells produced a protein which was immunoreactive to an antibody against P450cc24. When the cell-free extract of the transformed cells was incubated with calcidiol together with bovine adrenodoxin and NADPH-adrenodoxin reductase, not only hydroxycalcidiol but also other metabolites such as oxocalcidiol and oxohydroxycalcidiol were produced. Similarly, calcitriol was converted not only to Calcitetrol but also to oxocalcitriol and oxohydroxycalcitriol. These results indicate that a single enzyme expressed in the bacteria is responsible for all these successive reactions.
