Analysis Note

liquid or solid

Application

Spermidine has been used:as a component of chromosome isolation bufferas a component of transcription bufferas a component of homogenization buffer

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.

Spermidine modulates various cellular activities like cellular growth and development, stability of DNA and apoptosis.

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.

General description

Spermidineis a polyamine and a trivalent organic cation.
