Description and Uses

Spermidine is an endogenous polyamine. It is formed from putrescine by spermidine synthase.

Spermidine can be used in electroporation while transferring the DNA into the cell under the electrical impulse. May be used for purification of DNA-binding proteins. Spermidine is also used, along with calcium chloride, for precipitating DNA onto microprojectiles for bombardment with a gene gun.
