Amino acid transport System A has previously been demonstrated in apical membranes derived from rat placenta, as well as in apical and basal membranes derived from human placenta. We have studied Na(+)-dependent alpha-(methylamino)isobutyric acid (MeAIB) transport in apical and basal predominant membrane fractions prepared from 14 and 20 day gestation rat placenta. Marker enzyme recoveries did not differ significantly between age groups. Markers for intracellular organelles were also found to… CONTINUE READING
