αA-Conotoxin OIVA
Cat No.
CEI-1181
Description
αA-Conotoxin OIVA (αA-OIVA) is a peptidyl toxin originally isolated from Conus obscures and belongs to the family of short αA-conotoxins (αAS) which includes αA-OIVA, αA-OIVB, αA-PeIVA, and αA-PeIVB. αA-Conotoxin OIVA blocks the fetal muscular subtype nicotinic acetylcholine receptor (α1/β1/γ/δ subunits) (IC50 = 0.51 nM) with 600-fold greater affinity than the adult subtype (IC50 = 310 nM). It completely blocks the elicited currents and it dissociates very slowly from the fetal muscle receptor. This toxin causes an apparently irreversible paralysis upon intramuscular injection into gold fish.
