Spermidine

Spermidine is a polyamine involved in cellular metabolism that can be used to stimulate the enzyme, T7 RNA polymerase, a type of RNA polymerase.

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.

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.
