Ion channels are specialised pore-forming membrane proteins that allow ions to pass through the channel pore. They are classifed by their gating mechanism (eg. voltage-gated, ligand-gated, cyclic-nucleotide-gated & mechanosensitive) or ion selectivity (eg. calcium, potassium, sodium, chloride, proton). Researchers can save up to 50% on selective ion channel activators and blockers from Hello Bio - they are up to half the price of other suppliers.
