General description

Flavin adenine dinucleotide disodium salt hydrate (FAD-Na2) is an adenine-containing enzymatic redox cofactor. Also known as flavin cofactors, FAD is critical electron transporter in living systems. They catalyze several 1-2 electron redox reactions. e.g., β-oxidation of fatty acids occurs in the presence of FAD as a cofactor. FAD is one of the two active coenzymes of vitamin B12(riboflavin). FAD displays a significantly shorter excited state lifetime in aqueous solutions than its analog, flavin mononucleotide.

Application

FAD is used to remove reactive oxygen species (ROS) from mammalian cells. The fluorescence mechanism of FAD is used to study energy-dependent intramitochondrial redox potential. FAD is used as a predominant fluorophore to study unstained eosinophils, which exhibit autofluorescence compared to other leucocytes.
Flavin adenine dinucleotide (FAD) is used as a redox cofactor (electron carrier) by flavoproteins including succinate dehydrogenase (complex), α-ketoglutarate dehydrogenase, apoptosis-inducing factor 2 (AIF-M2, AMID), folate/FAD-dependent tRNA methyltransferases, and N-hydroxylating flavoprotein monooxygenases. FAD is a component of the pyruvate dehydrogenase complex.
