Cy5-ProTx-II

• Description:

  Cy5-ProTx-II is a fluorescently labeled ProTx-II, a famous Nav1.7 blocker. The wild type ProTx-II blocks Nav1.7 with an IC50 value of around 300 pM, Nav1.2, Nav1.5 and Nav1.6 with IC50 values of 41 nM, 79 nM and 26 nM respectively. The Cy5-ProTx-II version developed by Smartox has potent Nav1.7 blocking activity. It was shown to fully block Nav1.7 at 100 nM concentration
