noun[mass noun] Biochemistry
A colourless compound with a similar distribution and effect to spermine.
- The present study indicates that DNA resolubilization at high concentrations of spermine and spermidine is explained by formation of small particles of condensed DNA that cannot be precipitated by centrifugation.
- These specificities lead to preferential bindings through the DNA minor groove for putrescine and spermidine, whereas spermine binds by the major groove.
- Maybe even higher efficiencies would have been obtained using spermine instead of spermidine.
