The Indolamine 2,3-Dioxygenase 1 (IDO1) Activity Assay Kit (ab235936) enables the easy determination of IDO1 activity in mammalian tissues and cell lines. The assay uses a fluorogenic developer that selectively reacts with N-formylquinurenine (NFK) to produce a highly fluorescent product (Ex / Em = 402/88 nm), ensuring a high signal/background ratio. The kit also includes… Continue reading
