Spermidine trihydrochloride (99%-101%)

Spermidine inhibits neuronal nitric oxide synthase (nNOS). As it bind to DNA it might be used as precipitation agent for DNA-binding proteins. Spermidine stimulates T4 polynucleotide kinase activity.

As Spermidine and Spermidine hydrochloride deaminates over time, solutions should be sterile-filtered, not autoclaved, if sterile solution is necessary. For the same reason prepare new solutions frequently.
