Alomone Labs -Conotoxin GIIIA blocks NaV1.4 currents in Xenopus oocytes. - A. Time course of-Conotoxin GIIIA(#STC-280) action on maximum NaV1.4 current amplitude. Maximum peak current amplitudes were plotted as a function of time. Membrane potential was held at -100 mV and oocytes were stimulated by a 100 ms voltage step to 0 mV. 100 nM -Conotoxin-GIIIA was perfused as indicated by the bar (green) for 5 min. B. Superimposed examples of NaV1.4 channel peak current in the absence (control) and presence (green) of 100 nM -Conotoxin-GIIIA (taken from the experiment in A).
product information
cat :
STC-280
SKU :
STC-280_0.1 mg
Product Name :
µ-Conotoxin GIIIA
Group Type :
Non Antibodies
Product Type :
Proteins
Accession :
P01523
Accession Number :
https://www.uniprot.org/uniprotkb/P01523/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 :
μ-Conotoxin GIIIA is a peptide toxin originally isolated from the venom of Conus geographus. It specifically blocks skeletal muscle Na+ channels (NaV1.4) with an IC50 of 1500 nM1.NaV channels are targets for many toxins, which bind with high affinity to various sites on the channel protein, µ-Conotoxin selectively binds to the NaV1.4 channel, blocks the pore and disabling its normal function, act as an antagonist for VGSCs1.Voltage-gated NaV channels (VGSCs) play a key role in the electric excitability of cells by regulating the influx of sodium ions. VGSCs are responsible for initiating and propagating action potentials, which are essential for the activity of a wide selection of cells and tissues such as neurons, heart and muscle. In mammals, nine different subtypes (NaV1.1-1.9) have been identified, each with distinct distribution.VGSCs acts as a potential drug targets for related disorders such as cardiac and neuropathic diseases2,3.
