Table 3. Spermine block rates in GluA2 receptors.

Receptor Permeant blocker model n
kon koff kperm Kd(0mV)
a (µM−1s−1) b (mV) c (s−1) d (mV) e (s−1) f (mV) (µM)
GluA2 29 113 156 −19 32 20 6 7
SEM 5 13 30 1 16 3 1

Block rate parameters were obtained by fitting the current relaxation after the voltage steps.
