A unique collection of hands-on enzyme assay techniques to study polyamines and their function. The techniques range from assay methods for enzymes of polyamine biosynthesis and catabolism to measurements of polyamines, polyamine transport, and polyamine effects on cell growth...

Putrescine and spermidine are ubiquitous in living organisms. Spermine, third of the three most commonly occurring natural polyamines, is probably present in all eukaryotes but is rare (or nonexistent) in prokaryotes. Polyamine residues are constituents of many compounds found...
