CAS 71-44-3 Spermine N,N'-Bis(3-aminopropyl)-1,4-diaminobutane Natural Polyamine
Spermine is a natural polyamine found ubiquitously in all living cells. It is a tetramine (containing four amino groups) derived from the sequential addition of aminopropyl groups to putrescine. It plays critical roles in cellular growth, proliferation, differentiation, and survival. In biochemical research, it is primarily used as a tool to study polyamine metabolism, as a component in cell culture media, and as a stabilizing agent for nucleic acids.
