Shipping Temperature
The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture.
Storage Conditions
Storage as Solution: The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods (up to 6 months), small aliquots should be stored at -20°C. We do not recommend storing the product in working solutions for longer than a few days. Avoid multiple freeze-thaw cycles. - Storage before Reconstitution: The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture. - Storage after Reconstitution: The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods (up to 6 months), small aliquots should be stored at -20°C. We do not recommend storing the product in working solutions for longer than a few days. Avoid multiple freeze-thaw cycles.

Short description
A Blocker of NaV1.7, NaV1.5 and NaV1.4 Na+ Channels
Description
β/ω-TRTX-Gr2a, Toxin GTx1-15, Beta/omega-theraphotoxin-Gr2a - A Blocker of NaV1.7, NaV1.5 and NaV1.4 Na+ Channels
Reconstitution
Centrifuge the vial (10, 000 × g for 5 minutes) before adding solvent to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Gently tap, tilt, and roll the vial to aid dissolution. Avoid vigorous vortexing; light vortexing for up to 3 seconds is acceptable if needed. The product is soluble in pure water at high micromolar concentrations (100 µM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity.

Scientific Background
GpTx-1 is a 34-residue peptide with inhibitory cystine knot motif and contains 3 important residues near the C-terminus that are critical for potently blocking NaV1.7 channel, with IC50 value of 10 nM The peptide toxin was originally isolated from the Grammostola porteri spider venom1, 2. In addition, GpTx-1 demonstrates selectivity against other NaV subtypes including NaV1.4 and NaV1.5 channels.There are nine mammalian subtypes of voltage-gated sodium (NaV) channels: NaV1.1-NaV1.9. These channels responsible for propagating action potentials in excitable cells and are considered to be important therapeutic targets for a wide variety of pathophysiological conditions such as cardiac arrhythmia, and epilepsy. NaV1.7 channel plays an important role in human pain signalling pathway and it is an important therapeutic target for treatment of chronic pain3, 4.
