It is used in industrial applications such as dyeing, porcelain glazing, and the manufacture of fertilizers and boiling oils. Used in cell culture experiments. MnSO4 is used as a source of manganese ion in biological research, such as in culturing of Bacillus licheniformis and the induction of chromosomal abnormalities in plants. MnSO4 has been utilized to investigate the enzyme dependent glycosylation of endogenous glycoproteins in human skeletal muscle. A protocol that uses MnSO4 in the removal of contaminating genomic DNA in RNA samples for RT- PCR has been published.
