Calcium-dependent pro-cholecystokinin V-9-M immunoreactive peptide release from rat brain slices and CCK-secreting rat medullary thyroid carcinoma cells in culture.

abstract：:[3H]Neurotensin (NT) was found to bind specifically and with high affinity to crude membranes prepared from rat uterus. Scatchard analysis of saturation binding studies indicated that [3H]NT apparently binds to two sites (high affinity Kd 0.5 nM; low affinity Kd 9 nM) with the density of high affinity sites (41 fmoles...
