Calcium binding by parathyroid cell plasma membranes.

Parathyroid hormone (PTH) secretion from parathyroid glands is controlled mainly by extracellular calcium both in vivo and in vitro. In this study, the Ca2+ binding properties of bovine parathyroid cells have been investigated on a highly purified plasma membrane preparation with flow dialysis techniques. Scatchard plot analysis of the data shows the… (More)
