  • Handling

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

  • GsMTx-4 (ab141870) inhibits NaV1.7 channel currents expressed in Xenopus oocytes. NaV1.7 currents were elicited by 100 ms voltage ramp from a holding potential of -100 mV to +30 mV, applied every 10 seconds using whole-cell voltage clamp technique. Left: Superimposed traces of NaV1.7 currents before (black) and during (green) application of 500 nM GsMTx-4 (ab141870). Right: GsMTx-4 dose response inhibition of NaV1.7 currents.
