Nigericin effect on ph
http://www.cnreagent.com/s/sv75647.html WebNigericin (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 ...
