Apamin vs Conotoxin

Apamin vs Conotoxin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Apamin
Venom Peptide

Apamin is an 18-amino acid peptide neurotoxin from bee venom (Apis mellifera), notable as one of the smallest naturally occurring neurotoxic peptides. This pharmacological selectivity has made apamin an invaluable tool for dissecting SK channel contributions to neuronal excitabil...

Conotoxin
Venom Peptide

Conotoxins (conopeptides) are a diverse superfamily of small, disulfide-rich peptide toxins produced by predatory cone snails (Conus species). With >10,000 predicted sequences across ~700 Conus species, conotoxins are an extraordinary reservoir of pharmacologically selective tool...
