The dopamine content of either cortical slices or isolated glomeruli prepared from rat kidneys and of their incubation medium was measured at different times both under basal conditions and in the presence of L-DOPA. Production of dopamine from L-DOPA by purified cytosolic proteins of the whole cortex was also measured. Dopamine synthesized by these 3 renal(More)
Tritiated salmon calcitonin was prepared by methylation of the free amino groups using tritiated sodium borohydride as precursor. Specific radioactivity was measured in competitive inhibition studies with specific anticalcitonin antibodies or tubular membranes as binding sites for calcitonin. The value observed, approx. 4 Ci/mmol, corresponded to(More)
