Description: 6-FAM-AEEAC-SHK TFA, a peptide neurotoxin derived from Stichodactyla helianthus and conjugated with a fluorescent marker, selectively blocks voltage-gated potassium channels (kv1.1 and kv1.2). By prolonging action potentials, it interferes with neural signal conduction, making it valuable in neuroscience research.
Formula: C196H295N55O57S7.xCHF3O2
Molecular Weight: 4558.23 (free acid)
