Figure 1. Transport of UDPGA into rat liver and hepatoma cell line microsomes.
The time- and UDPGlcNAc-dependent uptake of [14C]UDPGA was investigated both in rat liver microsomes (A) and in microsomes prepared from H4IIEcells (B). Rapid filtration assays were started after 90 min of pre-incubation with 1mM UDPGlcNAc (●) or water (○) at 37 °C. Error bars represent the means±S.D. (n=4–6).
