Caution
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.
Other Notes
In first strand cDNA synthesis1; Effect on endonuclease inhibition by agarose contaminants2
Biochem/physiol 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.

Caution
如果需要无菌溶液，则应采用无菌过滤而非高压灭菌。时间一长，亚精胺将发生脱氨基作用；溶液应采用冷冻保存。通常需要配制新溶液。
