[edit] Biochemical actions

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

[edit] Safety

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.
