Alomone LabsFluoxetine hydrochlorideblocks KV4. 3 channels expressed inXenopusoocytes. - A. Time course of KV4.3 current amplitude and inhibition by 100 MFluoxetine hydrochloride(#F-155). Currents were elicited by application of voltage step from a holding potential of -80 mV to 0 mV (150 msec) every 10 seconds. B. Superimposed example traces of current responses before and during perfusion of 100 M Fluoxetine hydrochloride as indicated.
product information
cat :
STP-150
SKU :
STP-150_0.1 mg
Product Name :
ProTx-III
Group Type :
Non Antibodies
Product Type :
Proteins
Accession :
P0DL64
Accession Number :
https://www.uniprot.org/uniprotkb/P0DL64/entry
Applications :
Electrophysiology
Formulation :
Lyophilized from double distilled water (ddH2O). May contain TFA as a residual counter ion.
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.
Reconstitution and Solubility :
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.

Product Page - Scientific background :
ProTx-III (µ-TRTX-Tp1a) originally isolated from the venom of the peruvian green-velvet tarantula Thrixopelma pruries, is a potent blocker of voltage-gated sodium (NaV) channels, with highest affinity towards NaV1.7 with an IC50 of 11.5 nM, and demonstrates analgesic properties in in vivo models1.NaV channels are responsible for initiating action potentials in electrically excitable cells. They play an important role in the human pain signalling pathway and are important therapeutic targets for treatment of chronic pain. Mutations in NaV channels are also associated with a range of complex pathologic conditions such as epilepsy, myotonic conditions and cardiac arrhythmias1,2.
