Shipping Temperature	The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture.
Storage Conditions	Storage as Solution: 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. - Storage before Reconstitution: The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture. - 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.
Molecular Weight	3037 Da

Short description	A Blocker of N-Type Ca2+ Channels
Description	SNX-124 - A Blocker of N-Type Ca2+ Channels
Reconstitution	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.

Scientific Background	ω-Conotoxin GVIA is a synthetic toxin originally isolated from the Conus geographus. ω-Conotoxin GVIA is a specific blocker of CaV2.2 Ca2+ channels. It specifically blocks N-type CaV channels by binding to the CaV2.2 α1 subunit (α1B) and its action is only partially reversible.2, 3 In accordance, it inhibits synaptic transmission in many systems.4 It is also reported to antagonize P2X receptors.5 The toxin is used to specifically investigate CaV2.2 channel's contributions (by subtraction of the activity before and during perfusion of the toxin). Alternatively, it is used to eliminate the N-type channel contribution to highlight some other channel or enzyme activity. ω-Conotoxin GVIA was also used to purify the channel protein using immunoprecipitation techniques and to label and localize channels and synapses.6
