Vitamin D3 ELISA kits are assays designed to detect vitamin D3, also known as cholecalciferol. It is synthesized from 7-dehydrocholesterol by the skin when exposed to UVB radiation. Vitamin D3 facilitates bone growth and mineralization by enhancing plasma calcium and phosphorus levels. The active metabolite of vitamin D3 is calcitriol (1,25-dihydroxyvitamin D3). It is used for the treatment of hypoparathyroidism and Fanconi syndrome. Visit the supplier page for more information about detection target, range and reactivity
