Putrescine Dihydrochloride by Molecular Depot is a putrescine dihydrochloride, the four-carbon diamine at the start of the polyamine pathway. Putrescine is made from ornithine by ornithine decarboxylase, the rate-limiting step of polyamine synthesis, and it is the precursor from which spermidine and spermine are built. It is used as a polyamine supplement in cell and neuronal culture media, as a substrate in polyamine oxidase and transport assays and in polyamine metabolism research. Each unit contains 100 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
