Activation time constants at room temperature

Current	τ, ms	n
Remaining (after Kv1 and Kv2 block)	137 ± 23	6
Linopirdine sensitive (3 μM)	143 ± 19*	16
XE-991 sensitive (0.5–1 μM)	206 ± 34*	11
Muscarine/Oxo sensitive	134 ± 11	8
ScTx sensitive	69 ± 21	4
Kv2.1 antibody sensitive	75 ± 25	4
DTX sensitive	11 ± 1	33

Values are means ± SE (n = no. of cells) for activation time constant τ at −10 mV. Data for current sensitive to stromatoxin (ScTx; putative Kv2 channels) and for current sensitive to intracellular application of a Kv2.1 antibody (Kv2.1 channels) are from Guan et al. 2007a. Data for current sensitive to α-dendrotoxin (DTX; putative Kv1.1, Kv1.2, and Kv1.6 channels) are from Guan et al. 2006. Muscarine/Oxo sensitive, current sensitive to muscarine (0.3–1 μM) or oxotremorine (10 μM).

^*P < 0.05, significant difference from whole current or blocker-resistant current.
