USP, PH.EUR. grade Magnesium Chloride Hexahydrate is widely used as a source of magnesium ion in chemistry and molecular biology applications. In biological systems, magnesium is a co-factor for many enzymes including deoxyribonuclease (DNase) and various restriction enzymes. It is essential for the function of DNA polymerase in polymerase chain reaction (PCR) amplification. In addition, Magnesium chloride hexashydrate plays a role in cellular learning, cell membrane integrity, muscle cell physiology, cardiovascular and muscular activity, and nucleic acid structure.
