Preparation of NE subfractions. (A) Illustrates schematically the architecture of the nucleus of a eukaryotic cell with emphasis on the NE compartments. The frame indicates the substructures present in the NE preparation. (B) Fractionation scheme applied to the fractionation of the NE. (C) Distribution of the marker proteins calnexin (ONM/ER membrane), LAP 2β (INM), and lamin B1 (nuclear lamina) throughout the different NE subfractions. Calnexin is absent from the TX-100-resistant fraction; lamin B1 is almost absent from the chaotrope-resistant fraction.
