Product Overview

alpha-Conotoxin SI (CAS 115797-06-3) is a highly specific neurotoxic peptide originally isolated from the venom of the marine cone snail Conus striatus. This short-chain peptide consists of 13 amino acids with two essential disulfide bridges that stabilize its rigid bioactive conformation. Within the Peptides and pharmacological research sectors, alpha-Conotoxin SI is critically valued for its technical capacity to act as a potent antagonist of nicotinic acetylcholine receptors (nAChRs), particularly at the neuromuscular junction in various laboratory models. As a leading manufacturer of alpha-Conotoxin SI CAS 115797-06-3 based in China, Conscientia Industrial utilizes advanced solid-phase peptide synthesis (SPPS) and sophisticated HPLC purification strategies to ensure precise folding and structural integrity. Our product maintains a strict purity profile and verified disulfide connectivity to meet the most demanding global technical requirements for ion channel research, neurobiology studies, and advanced biochemical assay development.
