Description

Application

Magnesium sulfate solution has been used:

• as a component in super optimal broth with catabolite repression (SOC) medium for culturing Escherichia coli[1]
• as a component in transition media for culturing human umbilical vein endothelial cells (HUVEC)[2]]
• as a component in M9 buffer for worm fixation prior to nuclei extraction[3]

Biochem/physiol Actions

Magnesium sulfate has anti-convulsant, anti-inflammatory and vasodilatory properties. Magnesium sulfate relaxes smooth muscles.[4] In acute asthma patients, use both intravenous and nebulization of magnesium sulfate as additive treatment improves pulmonary function.[4][5] Magnesium sulfate reduces preterm labor in high risk pregnant women.[4]
