The techniques used to detect and quantify cyanocobalamin (vitamin B12) vary considerably in terms of detection sensitivity, from the most sensitive, based on radioisotopes and mass spectrometry (MS) with limits of detection (LOD) in fg mL1, to fluorescence (FL) and surfac...
Hydroxocobalamincombines with cyanide in an equimolar ratio to formcyanocobalamin[79]. Cyanocobalamin is also known as vitamin B-12; it is nontoxic and renally eliminated. View article Review article Significance of elevated cobalamin (vitamin B12) levels in blood ...
