Abstract
Programmed necrosis, also known as necroptosis, is a form of regulated necrotic cell death that is mediated by receptor-interacting protein kinases RIP1 (or RIPK1), RIP3 (or RIPK3), and the mixed lineage kinase domain-like protein, MLKL. Following the induction of programmed necrosis, MLKL is phosphorylated by RIP3 and oligomerizes and then the protein translocates to cell plasma membrane in order to execute programmed necrosis. Here, we describe a detailed protocol to detect MLKL oligomerization in necroptotic cells by Western blotting analysis under nonreducing condition. Therefore, we established the method to detect the activation of programmed necrotic pathway.
