Table 3. Energy-dependence of the uptake of L-[3H]carnitine by HCLE or HCjE cells at pH 7.5 and 37 °C.

  Relative uptake (% of control)
Compound HCLE HCjE
Sodium azide 80.4±1.8 79.2±1.3
Dinitrophenol 69.1±4.7 63.1±7.6
Iodoacetic acid 27.2±6.3 27.8±3.3

HCLE or HCjE cells were pre-incubated for 30 min in uptake buffer containing 10 mM of sodium azide, dinitrophenol or iodoacetic acid; L-[3H]carnitine (24 nM) was then added and the incubation continued for 30 min. Each value is the percentage uptake of L-[3H]carnitine in medium containing sodium azide, dinitrophenol, or iodoacetic acid compared with that in control medium without these compounds. Values are the mean±SD of results from four experiments.
