A method is described which allowed in-vitro measurements of metabolic CO2 production from [U-14C]-substrates by single pieces of kidney tubules. The tubules were isolated by microdissection from collagenase treated rat kidneys. Single pieces of various distal nephrons portions were incubated in 1 microliter of bicarbonate free minimum essential medium containing the required [U-14C]-substrate (about 0.2 mu Ci per sample), and the 14CO2 produced was continuously trapped into a 2-microliter KOH droplet. The KOH droplets were replaced every 30 min. Metabolic CO2 production from the labelled substrate used was calculated as picomoles CO2 per mm of tubular length per minute, by dividing the KOH radioactivity by the specific radioactivity per carbon of the substrate present in the incubate [( U-14C] plus cold substrate concentrations). Under these conditions, it was established that single pieces of tubule could sustain almost constant CO2 production for at least 2 h at 31 degrees C. Experiments testing four different conditions with five to six replicate samples per condition were performed in order to compare oxidative metabolism in medullary (MAL) and cortical (CAL) thick ascending limbs, medullary (MCT) and cortical (CCT) collecting tubules and, in a few instances, proximal convoluted tubules (PCT) and early distal convoluted tubules (DCT).(ABSTRACT TRUNCATED AT 250 WORDS)
