Spermidine is a polyamine involved in cellular metabolism that can be used to stimulate the enzyme, T7 rna polymerase, a type of RNA polymerase.
Contents |
- Inhibits neuronal nitric oxide synthase (nNOS).
- Binds and precipitates DNA.
- May be used for purification of DNA binding proteins.
- Stimulates T4 polynucleotide kinase activity.
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.
