Zinc sulfate is used in various manufacturing processes, such as calico printing, wood preservation, the production of lithopone, and the bleaching of paper. A study of the abscissic acid transduction cascade in Arabidopsis thaliana has used zinc sulfate as an anion channel blocker. The use of zinc sulfate to investigate the internal speciation of zinc in the roots and leaves of Phaseolus vulgaris has been described. Zinc sulfate has been utilized to induce metallothienin expression in mice. Several protocols that use zinc sulfate for protein precipitation and analysis by LC/MS have been published. A procedure has been reported on the use of zinc sulfate to remove hemoglobin from mammalian tissue cytosol for subsequent study of lipoxygenase activity from biological samples.
