The nuclear proteome has recently gained importance in basic and applied research due to the fact that identification of novel nuclear proteins helps to understand protein functions and protein-protein/protein-nucleic acid interactions. Currently there just a few commercial kits available for isolation of plant nuclei. Following table is a side by side comparison of two major brands.
