Poneratoxin is the modulator for voltage-gated sodium channel (NaV, EC₅₀ for NaV1.6 and NaV1.7 is 97 nM and 2.3 µM), that lowers the voltage threshold for activation and inhibits the inactivation of channels, enhances the excitability of neurons, and leads to the transmission of pain signals.

Biological Activity

Description

All Sodium Channel Isoforms :

In Vivo

Poneratoxin causes immediate and long-lasting nocifensive behaviours (20 to 600 pmol, intraplantar injection, single dose) in C57BL/6 J mice model, and leads to paralysis with PD₅₀ (1 h) of 74.3 nmol/g in blowflies model (0-100 nmol/g, ip, single dose)^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
