Electrophysiology

Lyophilized from double distilled water (ddH2O). May contain TFA as a residual counter ion.

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.

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.

The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture.

Phlogius sp. (Tarantula spider)

Synthetic peptide

SCN9A

Phlo1b is a NaV1.7 channels blocker, originally isolated from the venom of the Australian Phlogius sp. Tarantula. The peptide toxin is a gating modifier that inhibits NaV1.7 activation through its interaction with one or more voltage-sensor domains and displays an IC50 value of 0.36 µM1.Phlo1b is a 35-residue peptide that belongs to the NaSpTx2 family and is a valuable research tool and lead molecule for the development of ion channel therapeutics. NaSpTx2 family peptides contain three disulfide bonds and they share highly stable inhibitor cystine knot (ICK) fold that provides resistance to chemical and thermal degradation1.There are nine mammalian subtypes of voltage-gated NaV channels: They are 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 the human pain signaling pathway and it is an important therapeutic target for treatment of chronic pain1,2.
