Magnesium Chloride Hexahydrate
CAS NO: 7791-18-6
MOLECULAR FORMULA: MgCl2•6H2O
MOLECULAR WEIGHT: 203.30
Application: Magnesium Chloride, Hexahydrate is a source of magnesium ion and a co-foactor for many enzymes Purity: >99% Molecular Weight: 203.3 Molecular Formula: MgCl2•6H2O Description: 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. Also plays a role in cell membrane integrity, muscle cell physiology, cardiovascular and muscular activity, and nucleic acid structure. Magnesium chloride solution is a favorable choice as an elution buffer for antibody affinity column purifications; it is much milder on most antigens than acid elution, allowing reuse of the antigen column. Also an essential cofactor for the DNA polymerase in polymerase chain reaction (PCR) amplification. Physical State : Solid Solubility : Soluble in water (20 mg/ml), and alcohol. Storage : Store at room temperature Melting Point : 116-118° C (dec.) Density : 1.57 g/cm3 at 20° C
