Quantification of protein complexes by blue native electrophoresis.

Blue native electrophoresis (BNE) is a long established method for the analysis of native protein complexes. Applications of BNE range from investigating subunit composition, stoichiometry, and assembly of single protein complexes to profiling of whole complexomes. BNE is an indispensible tool to diagnostically analyze cells and tissues from patients with mitochondrial disorders or model organisms.
