Blue native PAGE (BN-PAGE) permits a high-resolution separation of multi-protein complexes under native conditions. Blue native (BN)-PAGE is a charge shift method, in which the electrophoretic mobility of a complex is determined by the negative charge of the bound Coomassie dye and the size and shape of the complex. Coomassie does not act as a detergent and preserves the structure of complexes. Importantly, the resolution of BN-PAGE is much higher than that of other methods such as gel filtration or sucrose-gradient ultracentrifugation. Combined with other pre-purifications or dialysis steps this method permits the analysis of multi-protein complexes of whole cellular lysates by BN-PAGE. [ PMID:14665681 ]
