In vitro citrate synthesis by the dog kidney. Investigations with cortex, red and white medulla slices.
In vitro utilization or production of citrate by the cortex, outer medulla or inner medulla of dog kidney was measured. Our data show: 1. An in vitro citrate synthesis or utilization capacity of the cortex greater than that of the red medulla. 2. An effect of pH on citrate synthesis or utilization capacity of the cortex, an effect not seen with medullary slices. 3. An absence of citrate synthesis or utilization by white medulla slices. It would seem that the citrate found in the white medulla and the papilla of the dog kidney in vivo was not produced in situ.
