    The recent application of the patch-clamp technique to the study of single channels present in the ß-cell plasma membrane has led to the discovery of a channel the activity of which is inhibited by the application of ATP to the membrane cytoplasmic surface7. It has been suggested that this channel may be responsible for glucose-induced ß-cell depolarisation and that ATP may be the long-sought connection between glucose metabolism and the excitation of insulin secretion7,8. Cell lines are proving to be very convenient and reproducible systems with which to study metabolic processes and their regulation and we have found them particularly suitable for patch clamp procedures. We have therefore investigated a new insulin-secreting cell line5 using the patch-clamp technique in order to study potassium channels and their role in the control of insulin secretion.
