Abstract:
BN-PAGE (Blue Native-Polyacrylamide Gel Electrophoresis) is a non-denaturing electrophoretic technique used to analyze the molecular weight and oligomeric states of protein complexes under near-native conditions. NLRs (nucleotide-binding leucine-rich repeat proteins), which function as intracellular immune receptors in plants, form oligomeric higher-order complexes known as resistosomes upon activation by recognition of pathogen effectors-a mechanism elucidated through BN-PAGE and structural analyses. Here, we describe a method combining BN-PAGE with Agrobacterium-mediated complementation assay to investigate the resistosome formation of the NLR protein ZAR1 in Nicotiana benthamiana.
