WebMay 27, 2024 · They found that spermine blocks with ∼10-fold higher apparent affinity than spermidine. They also found that the block is voltage dependent, not surprising considering that the polyamines are positive cations, and that the voltage dependence of the block (zδ) is roughly similar between the two polyamines. WebJul 3, 2013 · The minimal concentration of spermine required to show an effect on the delayed rectifier was 200 μM. They suggested that this block was caused by spermine slipping rapidly in and out of the channel pore, a phenomenon called a “fast block” (Drouin and Hermann 1990, 1994).
