Provide independent access to the basolateral and apical domains of polar cells. Track-etched polyethylene terephthalate (PET) membranes have individual, cylindrical pores and are tissue culture-treated on both sides for cell growth. PET housing is not tissue culture-treated in order to limit cell growth on the side walls of the insert.
Translucent membranes for 0.4 and 3.0µm pore sizes have high pore density (HD) and are recommended for transport studies
Transparent membranes are recommended for visualization of live cells by light microscopy
Flanges on insert rim facilitate handling
For best results, use with tissue culture-treated Falcon Companion Plates
Transport studies, immunocytochemistry, electron microscopy, migration and invasion, and co-culture.
