The long-term stability of a stock solution stored at -20ºC has not been evaluated. It is recommended to prepare stock solutions in degassed water and store them in working aliquots in order to extend the stability. Solutions stored refrigerated are stable for 30 days. Frozen aliquots would be expected to be stable for at least as long as the refrigerated solution.

General description
Listen to an Audio Overview
Putrescine is an end product of fatty acid metabolism in dead tissues. It is a volatile diamine with pungent odour. It is synthesized by the decarboxylation of ornithine in the presence of enzyme, ornithine decarboxylase. Molecular docking studies reveal the binding of putrescine to human receptors called the trace amine-associated receptors (TAAR6 and TAAR8), present in olfactory epithelium.

Application
Biochem/physiol Actions
Putrescine is regarded as a marker of stress in plants. External supplementation of putrescine helps wheat plants to overcome drought stress. It is crucial for cell proliferation in animals and modulates abscisic acid (ABA) levels during cold stress in Arabidopsis plants. It serves as an attractant for predators.
Binds to the polyamine modulatory site of the NMDA receptor and potentiates NMDA-induced currents; precursor of spermidine.
