HWTX-III had no effect on the kinetics of activation and inactivation. The shift in the steady-state inactivation curve was distinct from other depressant spider toxins. WebThe purified rHNTX-III was further analyzed using a whole-cell patch-clamp assay. It was shown that the rHNTX-III was able to block currents generated by human Na v 1.7 (hNa v 1.7) at an IC 50 of 225 nM and also have high selectivity for different voltage-gated sodium channels. Therefore, it has very similar activity to the natural one. KEYWORDS: cloudflare ransomware
