Other Notes
Store under inert gas. Air sensitive; strongly hygroscopic.
Packaging
1, 5, 25 g in glass bottle
Application
Spermidine has been used:
• in the preparation of 5x transcription buffer[3]
• in the treatment of double-stranded RNA along with other reagents to increase the uptake of dsRNA by nematodes[2]
• as a standard in the analytical study of rat brain polyamines (185)
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.
General description
