Fluorescently-labeled toxins can be used to label or inhibit receptors or ion channels on neurons. Biotium offers these labeled with a variety of bright, stable CF® Dyes.  α-Bungarotoxin binds to the acetylcholine receptor. Cholera Toxin B binds to GM1 gangliosides in lipid rafts. Tetrodotoxin reversibly blocks excitable sodium channels. Transferrin binds to its receptor and is internalized by endocytosis. cAMP can be used to probe cAMP receptors.
