Sodium metatungstate (SMT) solution is an inorganic heavy liquid which is widely used in density fractionation. Sodium metatungstate (Sodium polyoxotungstates) is a potent and selective inhibitor of ecto-nucleoside triphosphate diphosphohydrolase (NTPDases, CD39) with Ki of 0.140 μM, 0.910 μM and 0.563 μM for NTPDase1, NTPDase2 and NTPDase3, respectively.
