Figure 5. Blocking effect of OCTN1 and/or OCTN2 antibody on the uptake of L-[3H]carnitine by HCLE or HCjE cells at 37 °C. HCLE or HCjE cells were pre-incubated for 60 min in uptake buffer containing OCTN1
(1:500) and/or OCTN2 (1:500) antibody at 37 °C; L-[3H]carnitine (24 nM) was then added and incubation was continued for 30 min. Each value is the mean±SD of results from three
experiments. *p<0.01 compared with the control group.
