Storage Instruction:Store the kit at 4°C. Description:
Vitamin D is bound in the blood to a binding protein (VDBP) and is metabolized in the liver to 25-OH vitamin D. 25-OH vitamin D has little biological activity, however, it comprises the most abundant of all circulating vitamin D metabolites. Its high affinity for the binding protein (VDBP) makes it the main storage form of vitamin D in the body. The serum/plasma concentration of 25-OH vitamin D is therefore widely accepted as the best indication of vitamin D supply. ALPCO’s 25-OH Vitamin D ELISA is manufactured by Immundiagnostik and exhibits outstanding sensitivity, measures both 25-OH Vitamin D2 and 25-OH Vitamin D3, and has excellent correlation to existing methods.
