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.

ω-Conotoxin CVIF is a peptide toxin originally isolated from Conus catus venoM It selectively blocks voltage-gated N-type Ca2+ channel and is being tested as a potential drug for the treatment of chronic and neuropathic pain. CVIF has a higher affinity for Ca2+ channels in their inactivated state.Neuronal (N)-type voltage-gated Ca2+channels (VGCCs) are involved in regulating neuronal excitability and nociceptive signals and play an important role in the transduction of acute and chronic pain perception. The VGCC channel residues that directly interact with ω-conotoxins, act at or near the outer vestibule of N-type (CaV2.2) and P/Q-type (CaV2.1) VGCCs1.CVIF can prevent the conduction of nociceptive signals from the peripheral to the central nervous system by inhibiting neurotransmitter release from primary afferent nerve terminals in the dorsal horn of the spinal cord1,2.CVIF has the ability to potently and selectively inhibit depolarization-activated Ba2+ currents through recombinant N-type Ca2+ channels in snails' oocytes1.
