Mfr.No.	STA-700-FRN, STA-700-FRN_10 mcg, STA-700-FRN_5 mcg
Description	A Fluorescent Conjugate Marker for Sensitive Detection of NaV Channels
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 lyophilized in 0.5 ml conical vial. The product is soluble in pure water to high-micromolar concentrations (5 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. Avoid exposure to light.
Background	ATX-II is a 47 amino acid peptidyl toxin, originally isolated from Anemonia sulcata sea anemone venom. It is a potent neurotoxin, which modulates voltage-gated Na+ channel gating kinetics by delaying its inactivation and prolonging the action potential of excitable membranes. ATX-II has been used as a powerful activator of TTX-sensitive and -insensitive Na+ channels in various excitable tissue and cell types (at concentration range of 10-100 nM)1-9.
Biological Activity	ATX-II potently modulates voltage-gated Na+ channel gating kinetics by delaying its inactivation and prolonging the action potential of excitable membranes. ATX-II has been used as a powerful activator of TTX-sensitive and insensitive Na+ channels in various excitable tissue and cell types1-9.
Formulation	Lyophilized from double distilled water (ddH2O). May contain TFA as a residual counter ion.
Molecular Weight	5561 Da
Solubility	The product is lyophilized in 0.5 ml conical vial. Centrifuge the vial before adding solvent (10,000 x g for 5 minutes). The lyophilizate 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. Soluble in pure water at high-micromolar concentrations (50 uM - 1 mM). For long-term storage in solution, it is recommended to prepare 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 at 10,000 x g for 5 minutes before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity. Avoid exposure to light
