Go to datasheet (ab120055)


What is the molecular weight of tetrodotoxin citrate? The datasheets for this product, ab120055, and tetrodotoxin, ab120054, give the same molecular weight (319.27) and same molecular formula (C11H17N3O8).


The water-soluble TTX citrate ab120055 is not a citrate salt, it is simply TTX that has been dissolved in a citrate solution, and then lyophilized. So, it has the same molecular weight and formula as ab120054, which is soluble in pH 4.8 citrate buffer to 100 mM.
