General description

Magnesium sulfate have anti-convulsant, anti-inflammatory and vasodilatory properties. Magnesium sulfate relaxes smooth muscles.[1] In acute asthma patient, both intravenous and nebulization of magnesium sulfate as an additive improves pulmonary function.[1][2] Magnesium sulfate reduces preterm labor in high risk pregnant women.[1] Magnesium sulfate heptahydrate serves as a source of Mg2+ ions in plant tissue culture medium,[3] and protoplast culture medium.[4]

Application

Magnesium sulfate heptahydrate has been used:
  • in the preparation of Scott′s tap water substitute as a bluing reagent for nuclear staining[5]
  • as a component of stabilization solution for the isolation of pituitary cells for matrix-assisted laser desorption/ionization mass spectroscopy (MALDI-MS)[6]
  • as an additive in the preparation of artificial sea water for the maintenance of Aplysia californica and in modified Gey′s balanced salt solution[7]
