Which ThinCert™ inserts are suitable for transport studies?
-
Due to their low protein absorption PET membranes are very well suited for transport studies. For this kind of application the pores of the membrane must be small enough to prevent cells from membrane passage. ThinCertTM cell culture inserts with 0.4 and 1.0 µm pores meet this criterion. In general membranes with a high pore density (translucent) give better results than membranes with a low pore density (transparent).
