Figure 2.

Temperature-sensitivity of the uptake of AEA (a, b) and OA (c, d) into ND7/23 cells. An incubation time of 5 min was used, and the data (means±s.e.m., n=4) are replotted either as added AEA/OA (a, c) or theoretical free AEA/OA (b, d) concentrations calculated as described in Materials and methods. The AEA data at 37°C shown in (a) are the same as the 5 min data points shown in Figure 1a, and can be used here since the data at 4°C were obtained concomitantly.
