Potassium sodium tartrate solution is a chelator used in multiple research applications; often used in heavy metal screening assays, colorimetric assays, and as a source of tartrate. A semi-quantitative method for screening heavy metals in biological material has been carried out by complexing metals with ammonium pyrrolidine dithiocarbamate, sodium diethyl dithiocarbamate and potassium sodium tartrate. In a procedure for a rapid colorimetric assay for determining gentamicin concentration, an alkaline copper tartrate (ACT) reagent solution was prepared containing potassium sodium tartrate (210 mol). Also used as a component of a one-step kit for labeling of oligonucleotides with 99mTc.
