Figure Lengend Snippet: Endothelial cell monolayer permeability cultureware and chamber systems. (a) Image of a 6-well culture plate with Costar Snapwell membranes on which the cells are grown. The Costar Transwell membranes (not shown) described in this protocol are similar, but smaller, in a 24-well plate configuration. (b) Schematic showing the configuration of the upper, “luminal” and lower, “abluminal” compartments with the endothelial cells grown on the Transwell insert in between. A tracer is added to the top compartment, and the rate of appearance of tracer in the lower compartment is measured to determine permeability of the cell monolayer. (c) Schematic of the configuration of the Ussing Snapwell chamber system, in which the “luminal” compartment is on the left and the “abluminal” compartment is on the right. Transport of the tracer from left to right across the endothelial monolayer is measured in order to determine permeability
Article Snippet: 8 For multiple Ps determination, a special chamber system with heating manifold base assembly and a circulating water bath are required (NaviCyte Ussing vertical chamber system available from Warner Instruments; part number 66-0075 for the base assembly; part number 66-0008 for Snapwell chambers).
