-|''' What is the effective concentration of digitonin for complete plasma membrane permeabilization?'''<br>
+|'''Same experimental conditions, but different O<sub>2</sub> fluxes in the left and right chambers?'''<br>
-It needs to be determined for each cell type and digitonin batch. The SUIT protocol SUIT-010 was designed to evaluate the optimum digitonin concentration to permeabilize the plasma membrane. <br>
+Check for instrumental and operational factors that could be causing O<sub>2</sub> flux differences between the O2k-chambers.
