Permeability Of Hydrophilic
Beginning of paper
SUMMARY
Investigations of the integrity and transport characteristics of 2/4/A1 cells
have been done in this report. The cell line was isolated from rat fetal
intestinal epithelial cells and transfected with thermolabile SV40 large T
antigen.
These cells proliferated at 33 °C, but eliminated the ....

.... Ohm.cm2, which was similar to the small intestine. In transport studies
2/4/A1 cell line monolayers selectively restricted the permeation of hydrophilic
permeability markers proportional to molecular weight and discriminated more
accurately between the molecules of intermediate molecular weight compared to
Caco-2 cells.
These results indicated that 2/4/A1 cells could be used as a model for
hydrophilic drug absorption.
INTRODUCTION
The small intestine plays a crucial role in the absorption ....
