Mfr.No.	STC-620, STC-620_0.1 mg, STC-620_0.25 mg, STC-620_0.5 mg, STC-620_1 mg, STC-620_10 mg, STC-620_5 mg
Description	A Potent Antagonist of Mammalian Muscle nAChR
Reconstitution	Centrifuge the vial (10,000 x 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 uM - 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.
Molecular Formula	C160H247N43O44S2
Background	alphaC-Conotoxin PrXA is a synthetic peptide purified to homogeneity, originally isolated from the Conus parius venom1. alphaC-Conotoxin PrXA reversibly blocks both adult and fetal mammalian muscle alpha1/beta1/epsilon/delta and alpha1/beta1/gamma/delta nicotinic ACh receptors1.
Biological Activity	alphaC-Conotoxin PrXA reversibly blocks both adult and fetal mammalian muscle alpha1/beta1/epsilon/delta and alpha1/beta1/gamma/delta nicotinic ACh receptor1.
Formulation	Lyophilized from double distilled water (ddH2O). May contain TFA as a residual counter ion.
Molecular Weight	3541 Da
Solubility	Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) 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. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. 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 uM - 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.

Storage	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. 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 of solutions: 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.
