The present study was aimed at kinetically characterizing the newly found carrier-mediated
riboflavin transport system in the rat colon, comparing it with that in the small intestine, and …

Carriers involved in riboflavin transport have generally been presumed to be localized in the
upper small intestine. However, using a closed loop technique, we found that in the rat colon …

The intestinal mucosal-to-serosal transport of riboflavin was examined using rat everted
sacs. Maximum transport of 0.5 μM riboflavin occurred in the proximal small intestine …

This study addresses the transport mechanism of riboflavin (vitamin B2) across intestinal
epithelium in the presence and absence of pharmacologically active compounds. A …

The first step of riboflavin absorption was studied by determining the uptake of the vitamin by
rat small intestinal brush border membrane vesicles. Vesicles were incubated at 25° C in the …

Transmural intestinal transport of riboflavin was studied in a concentration range between
0.033 and 10.0 µM by an in vitro perfusion technique by using everted jejunal segments of …

The intestinal transport of riboflavin in the immature intestine of the suckling rat (14 day old)
and its subsequent maturation in weanling (22 day old) and adult (90 day old) rats were …

The transport of riboflavin across the brush border membrane of human intestine was
examined using the established brush border membrane vesicle technique. Both osmolarity …

Transport of riboflavin across the intestinal brush border membrane in rats was studied
using the brush border membrane vesicle technique. Uptake of riboflavin into the membrane …

The uptake of riboflavin was studied in everted sacs of rat intestine using [14 C] riboflavin
and [3 H] polyethylene glycol to define the mechanism of mucosal membrane transport …
