Alomone Labs ?-Conotoxin MVIIC inhibits CaV2.2 heterologously expressed inXenopusoocytes. - A. Time course of?-Conotoxin MVIIC(#C-150) blocking action on CaV2.2 channels maximum current (expressing ?1B + ?2?1 + ?1 subunits). Maximum 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 ramp to 60 mV. 50 nM ?-Conotoxin MVIIC was perfused as indicated by the bar (green) for 160 sec. B. Superimposed examples of CaV2.2 channel peak current in the absence (control) and presence (green) of 50 nM ?-Conotoxin MVIIC (taken from experiment in A).

SKU :
C-150_0.1 mg
Product Name :
ω-Conotoxin MVIIC
Group Type :
Non Antibodies
Product Type :
Proteins
Accession :
P37300
Accession Number :
https://www.uniprot.org/uniprotkb/P37300/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 :
ω-Conotoxin MVIIC blocks CaV2.1 (α1A, P/Q-type) and CaV2.2 (α1B, N-type) channels.1 The toxin binds with high affinity to CaV2.1 and with lower affinity to CaV2.2 in rabbit brain.2 However, the block by ω-Conotoxin-MVIIC of N-type channels in DRG neurons developed much faster than the block of P-type currents in Purkinje cells.1 The effect of the toxin is modulated by voltage (i.e. it is more potent for inactivated channels).3In addition this toxin was reported to block nicotinic receptors (transiently expressed in Xenopus oocytes) with IC50 of 1.3 µM4 It was also shown to inhibit K+-induced 3H-GABA release in hippocampus in vivo.5 This effect was with high affinity (50% block, 200 nM). The toxin was used to inhibit synaptic transmission in several peripheral preparations.6,7
