  • Magnesium Chloride Hexahydrate

    CAS NO: 7791-18-6

    MOLECULAR FORMULA: MgCl26H2O

    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.

      Alternate Names:  Potassium Chloride is also known as KCl.
      Application:  Potassium Chloride is a common laboratory reagent and   calibration standard for measuring electrical conducivity.
      Purity:  >99%
      Description:  Potassium Chloride is commonly used as a laboratory reagent   as  a standard. Potassium Chloride may be used as a calibration   standard ionic solution for measuring electrical conductivity   because Potassium Chloride solutions, when prepared   carefully,  produce repeatable measurable properties.   Potassium  Chloride is also a good source of ionic chloride,   which should precipitate insoluble chloride salts upon addition   to a solution of an appropriate metal ion. Oral Potassium   Chloride is commonly used to replenish vital potassium in the   body, and has also been shown to lower blood pressure.   Potassium Chloride is commonly used in fertilizer.
