Polyamines are polycationic nitrogenous compounds that accumulate in plants exposed to abiotic stresses. In higher animals, they influence gene expression, brain development, and nerve growth and regeneration. Because of their known roles in plant stress responses, quantitative determination of polyamines is very important. Polyamines in their native form cannot be detected by optical and/or electrochemical methods as they do not show any structural features, and hence derivatization of polyamines is essential to make them to produce either chromophores or fluorescence. Here we describe various methods of derivatization using different labeling agents and suitable separation and detecting methods for a vast source of polyamines existing in living cells.

UI	MeSH Term	Description	Entries
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D011073	Polyamines	Amine compounds that consist of carbon chains or rings containing two or more primary amino groups.	Polyamine
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D019075	Electrophoresis, Capillary	A highly-sensitive (in the picomolar range, which is 10,000-fold more sensitive than conventional electrophoresis) and efficient technique that allows separation of PROTEINS; NUCLEIC ACIDS; and CARBOHYDRATES.
