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 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 …

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

Uptake of luminal riboflavin (RF) into the absorptive cells of rabbit small intestine was
examined using purified brush border membrane vesicle (BBMV) preparations. These …

The mechanism of riboflavin (RF) uptake by intestinal basolateral membrane vesicles
(BLMV) was examined in this study. BLMV were isolated by an established Percoll-gradient …

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 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 …

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 …

Background: Possible regulation of riboflavin (RF) intestinal uptake process by dietary
substrate level is not known and was examined in this study. Methods: RF uptake was …

Isolated rat enterocytes, both normal and those de-energized with rotenone, were used to
study the energy dependence of membrane and intracellular intestinal riboflavin transport in …
