Ion Channel Modulators

Custom Peptide Synthesis

Ion channel peptides are functional peptides that bind to and modulate specific ion channels. By activating or inhibiting channels such as calcium or potassium, they regulate cellular electrophysiological activity and are of great significance in neuroscience and cardiac physiology research.
