Spermine Tetrahydrochloride (Highly Pure) by Molecular Depot is a highly pure spermine tetrahydrochloride, the tetravalent polyamine of eukaryotic cells. Spermine carries four positive charges at physiological pH, which lets it bind along the phosphate backbone of DNA and RNA and condense and stabilise nucleic acid structures. It is used to condense and stabilise DNA in crystallisation and transfection work, as a polyamine supplement in cell culture and in nucleic acid structure and polyamine metabolism research. Each unit contains 100 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
