Merck, M2393-100G, Magnesium chloride hexahydrate

Application
Magnesium chloride hexahydrate (MgCl2·6H2O) has been used:
to prepare electrochemical substrate solution for surface treatment and immunoassay preparation of monoclonal anti-creatine kinase (CK-MB) antibody
as a component of casamino acids medium (Hv-Ca) to culture Haloferax volcanii strains
to prepare hydrated-salt poly(vinylidenefluoride)-hexafluoropropylene P(VDF-HFP)/MgCl2·6H2O nanocomposite film to study its phase transformation, surface morphology and dielectric property

Biochem/physiol Actions
Magnesium chloride is commonly used as a reagent in chemistry and molecular biology as a source of magnesium ions. Magnesium exhibits several biological roles in enzymology, cell membrane and wall structural integrity, muscle cell physiology, and nucleic acid structure. It functions as a co-factor in various enzymes, like deoxyribonuclease (DNAse), the restriction enzymes EcoRI and EcoRV, and Ribonuclease H. Magnesium stabilizes polymeric nucleic acids including ribozymes and transfer RNA.
