Product Info

Spermine and spermidine are both available as the hydrochlorides spermine tetrahydrochloride and spermidine trihydrochloride. The hydrochlorides are preferred by some researchers for their ease of use of the spermine and spermidine and have excellent shelf life capabilities. Spermidine is available as the phosphoric acid derivative Dispermidine Triphosphate which also has very good shelf life qualities. Spermine tetrahydrochloride is a clean white light density powered solid. Spermidine trihydrochloride is a clean white crystalline solid with excellent absorbance properties. The spermidine phosphate is a clean white powdered solid.
