Biologically active form of vitamin D3 in calcium absorption and deposition.
Biologically active form of vitamin D3 in calcium absorption and deposition. 1α,25-Dihydroxyvitamin D3 has widespread effects on cellular differentiation and proliferation, and can modulate immune responsiveness, and central nervous system function. Recent studies suggest that 1α,25-dihydroxyvitamin D3 acts as a chemopreventive agent against several malignancies including cancers of the prostate and colon and shows synergy with other anticancer compounds.
Cholecalciferol is an inactive form of vitamin D3 which undergoes various levels of hydroxylation to form active vitamin D3 analogs. 1α-Hydroxyvitamin D3 (alfacalcidol is a synthetic analog that is metabolized to 1,25-dihydroxycholecalciferol, the biologically active form of vitamin D3 in calcium absorption and deposition. 1α,25-Dihydroxyvitamin D3 has widespread effects on cellular differentiation and proliferation, and can modulate immune responsiveness, and central nervous system function. Recent studies suggest that 1α,25-dihydroxyvitamin D3 acts as a chemopreventive agent against several malignancies including cancers of the prostate and colon and shows synergy with other anticancer compounds.

  5. How can I dissolve Product D1530, ?,25-Dihydroxyvitamin D3, for cell culture use?

    1?,25-Dihydroxyvitamin D3 is soluble in serveral organic solvents, including methanol, ethanol, ethyl acetate, and tetrahydrofuran. For cell culture use, a 10 μM stock solution can be prepared and diluted to the working concentration in cell culture media.

  6. What is the best way to store stock solutions of Product D1530, 1?,25-Dihydroxyvitamin D3?

    1?,25-Dihydroxyvitamin D3 is both air and light sensitive, so should be stored under inert gas at either -20 or -70°C.  The length of time a stock solution can be stored depends on how carefully air is excluded from the solution. If care is taken to exclude air, stock solutions may be stable indefinitely at -20°C.

  7. I can't see anything in the vial. How should Product D1530, 1´,25-Dihydroxyvitamin D3, look?

    D1530 is packaged by dispensing a solution into the vials, then drying them under inert gas. The product will be a thin film in the bottom of the vial, so it may appear to be empty by visual inspection.
