Accession :

P56639

Accession Number :

https://www.uniprot.org/uniprotkb/P56639/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.

Origin :

Conus aulicus (Princely cone)

Source :

Synthetic peptide

Gene ID :

CHRNA3,CHRNB4

Product Page - Scientific background :

Small peptide toxins of Conus origin are highly useful tools for exploring ligand nicotinic acetylcholine receptors (nAChRs) interactions1. There are three α-conotoxin AuIs found in Conus aulicus: AuIA, AuIB and AuIC. α-Conotoxin AuIA is a 16 amino acid peptidyl toxin, belonging to neuronal α 4/7 subfamily of α-conotoxins. This toxin inhibits mammalian neuronal α3/β4 nicotinic acetylcholine receptor channels expressed in Xenopus oocytes. At relatively low concentrations (0.3 and 1.0 μM), this conotoxin is selective and inhibits only α3/β4 subtypes2.
