Product nameProTx-II, NaV1 channel blocker
DescriptionPotent, selective NaV1 channel blocker
Biological descriptionPotent, selective NaV1 channel blocker (IC50 values are 0.3 and 30-150 nM for NaV1.7 and other NaV1 subtypes respectively). Acts as a gating modifier similar to ProTX-I (Asc 1863) and shifts the voltage dependence of activation to more depolarized potentials. Selectively blocks the C-fibre compound action potential in vivo.

Solubility overviewSoluble in water
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 week. 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.
