Synonym: N,N'-bis(3-aminopropyl)-1,4-butanediamineSpermine is a naturally occuring polyamine that occursin all eukaryotes, but is rare in prokaryotes. It isessential for cell growth in both normal and neoplastictissue. 1 Spermine is formed through the addition of aaminopropyl group to spermidine by sperminesynthase. Spermine is strongly basic in character, and in aqueous solution at physiological pH, all of its amino groups will be positively charged. 3 A review of the role of spermine and other polyamines in affecting RNA structure and protein function has been published. 4 Spermine is commonly used in molecular biology and biochemistry research. The polycationic character of spermine in solution allows for its use in the precipitation of DNA of >100 base pairs in length from low salt aqueous buffers, and for the isolation of DNA from pulse field gels. 5,6,7 Spermine has also been utilized in chromosome isolation and in the aggregation of chromatin. 8,9 It may be used as a building block for the preparation of gene transfer agents. 10,11 The complexation of spermine with DNA
to form particles with diameter <100 nm has been studied. 12 Spermine has been used in the crystallization of DNA. 13,14
It has been reported that spermine interacts with the glycine binding site associated with the N-methyl- D-aspartate receptor complex. 15 Spermine has been
shown to inhibit the conversion of L-arginine to L-citrulline by neuronal nitric oxide synthase in cytosolic preparations of rat cerebellum and cultured cerebellar granule neurons. 16 In acute hippocampal slices, 1 mM spermine exerts a neuroprotective effect
by blocking the NMDA receptor and voltage-activated Ca 2+ channels. 17 The effect of spermine on MK-801 binding to recombinant N-methyl-D-aspartate receptors has been investigated. 18 Proteins and protein complexes have been crystallized using spermine. 19,20 Other applications of spermine include its use as a matrix in MALDI-MS for analysis of glycoconjugates and oligonucleotides. 21,22 Precautions and Disclaimer For Laboratory Use Only. Not for drug, household or other uses.
Preparation Instructions
This product is soluble in water (50 mg/ml), yielding a clear, colorless to light yellow solution. Storage/Stability Store at 2-8 °C. Solutions of spermine free base are readily oxidized. Solutions are most stable if prepared in degassed water and stored in frozen aliquots, under argon or nitrogen gas. References
