Nicotinic acid riboside is a NAD + precursor in human cells. Nicotinic acid riboside is an authentic intermediate of human NAD + metabolism. In Vitro Nicotinic acid riboside (HepG2 cells; 0.01 nM~0.1 mM) helps FK866-treated cells to maintain viability at low micromolar concentrations. .\nNicotinic acid riboside formation and release are caused by overexpression of FLAG-tagged CN-II and CN-III in HEK293 and HepG2 cells. CN-II and CN-III generate Nicotinic acid riboside in vitro by dephosphorylation of nicotinic acid mononucleotide (NAMN). MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
