Alomone Labs ω conotoxin mviid

Comparisons of effects of GV-58, GV-58 plus <t>ω-conotoxin</t> <t>MVIID,</t> and GV-58 plus tetrodotoxin (TTX) on the peak amplitude of I Na recorded from GH 3 cells. Cells were immersed in Ca 2+ -free Tyrode’s solution containing 10 mM TEA, and the pipettes used were filled with Cs + -containing solution. Current amplitude was taken at the beginning of the brief depolarizing pulse from −80 to −10 mV. Each bar indicates the mean ± SEM (n = 8 for each bar). Of notice, the peak I Na in GH 3 cells is subject to inhibition by TTX but not by ω-conotoxin MVIID. * Significantly different from control ( p < 0.05) and ** Significantly different from GV-58 (3 μM) alone group ( p < 0.05). Statistical analyses were made by one-way ANOVA among different groups ( p < 0.05).

Techniques Used: Inhibition

Effects of GV−58 on spontaneous action potentials (APs) recorded from GH 3 cells. Cells were bathed in normal Tyrode’s solution, and the recording pipettes were filled with K + −containing solution. When whole−cell configuration was established, we switched to the whole−cell current clamp recordings to measure changes in membrane potential, as current was set at zero. ( A ) Representative potential traces achieved in the absence (upper) and presence of 1 μM GV−58 (middle) or 3 μM GV−58 (lower). ( B ) Summary graph demonstrating effect of ω−conotoxin MVIID, GV−58, and GV−58 plus ranolazine (Ran) on the firing frequency of APs in GH 3 cells (mean ± SEM; n = 8). * Significantly different from control ( p < 0.05) and ** Significantly different from GV−58 (3 μM) alone group ( p < 0.05). Statistical analyses were made in one−way ANOVA among different groups ( p < 0.05).
