Description

ω-Conotoxin-So3 is a synthetic, biologically active peptide belonging to the ω-conotoxin family, a class of potent and selective N-type calcium channel blockers. This compound is a critical research tool for neuroscience and pharmacology, enabling the study of neuronal signaling, pain pathways, and ion channel function. It is primarily utilized by pharmaceutical researchers, academic institutions, and biotechnology companies engaged in neurological disorder research and novel analgesic development.

Application

• Neuroscience Research: As a selective inhibitor of N-type voltage-gated calcium channels (Cav2.2), it is essential for studying synaptic transmission, neurotransmitter release, and neuronal excitability.
• Pain Pathway Investigation: Used in preclinical models to elucidate the role of N-type calcium channels in nociception and to validate targets for chronic pain management.
• Ion Channel Pharmacology: Serves as a standard reference compound for screening and characterizing new calcium channel modulators and neuroactive agents.
• Drug Discovery & Development: A key tool compound in the research pipeline for developing next-generation, non-opioid analgesics and neurotherapeutics.
• Biochemical Assays: Employed in in vitro binding assays and functional studies to determine the potency and specificity of experimental compounds.
