Spermidine is a naturally occurring polyamine compound commonly found in food. It is essential for cell growth and survival, technique. Contact Technical Service for further support.

Inhibits neuronal nitric oxide synthase (nNOS). Binds and precipitates DNA, may be used for purification of DNA binding proteins. Stimulates T4 polynucleotide kinase activity.

Solutions should be sterile-filtered, not autoclaved, if sterile solution is necessary. Spermidine deaminates with time, solutions should be stored frozen. Prepare new solutions frequently.

Spermidine may be used as one of the reference standard for the determination of spermidine in biological samples by high performance liquid chromatography-electrospray ionisation–ion trap tandem mass spectrometry (HPLC–ESI–ITMS/MS).
