Nigericin (sodium salt): Image 1
Western blot analysis of extracts from mouse primary bone marrow-derived macrophage (BMDM) cells, untreated (-), or treated (+) with Lipopolysaccharides (LPS) #14011 (50 ng/ml, 4 hr) and Nigericin (sodium salt) (45 min) at the indicated concentrations. Western blot analysis was performed using IL-1β (D3H1Z) Rabbit mAb (Mouse Specific) #12507 (upper), Cleaved-IL-1β (Asp117) Antibody (Mouse Specific) #52718 (middle), or β-Actin (D6A8) Rabbit mAb #8457 (lower).

Confocal immunofluorescent analysis of mouse primary bone marrow-derived macrophages (BMDMs), untreated (left) or treated with Lipopolysaccharides (LPS) #14011 (50 ng/ml, 4 hr) followed by Nigericin (sodium salt) (15 μM, 45 min; right), using ASC/TMS1 (D2W8U) Rabbit mAb (Mouse Specific) #67824 (green). Blue = Hoechst 33342 #4082 (fluorescent DNA dye). Note the translocation of ASC to inflammasomes following stimulation with LPS and Nigericin (sodium salt).

Nigericin (sodium salt) is an electroneutral K+/H+ ionophore derived from S. hygroscopicus. This antibiotic is lipophilic and selectively causes efflux of potassium across mitochondrial membranes (1,2). The ion exchange can lead to disruption of membrane potential, changes in pH, and cell death making the compound useful for studying areas of interests such as apoptosis, mitosis, and the immune response (3).
