Phrixotoxin 3-NH2 TFA is a spider-venom peptide stabilized by multiple disulfide bonds, providing a rigid scaffold for ion-channel studies. Basic and hydrophobic residues form complementary surfaces for voltage-gated channel binding. Researchers characterize its structure via NMR and electrophysiological assays. Applications include toxin-motif research, channel selectivity mapping, and disulfide-rich peptide engineering.
