When the data is compared to the healthy sample, we can see that Jareds H+ concentration decreases by .27 mM, his pyruvate concentration remains the same at . We will be able to tell very quickly from your data if 2 uM oligomycin is needed. In vitro. For example, 0.5 µM oligomycin was found to be sufficient to achieve maximal inhibition of OCR in HeLa cells (data not shown). Explain how the data from your experiments showed that cyanide was used to poison Jared, and that 2-deoxyglucose, arsenic and oligomycin were not used. Our bioassay. Furthermore, as the maximal effective concentration of FCCP may vary depending on the different energy substrate provided [1], optimal concentrations of FCCP were ascertained for both glucose and palmitate. Hence this demonstrates the resilience of the F 0 F 1-ATPase enzyme to function even after incubation with a relatively high concentration of oligomycin, an inhibitor of oxidative phosphorylation. Reacting condition. A concentration of 1 mM KCN is sufficient to inhibit oxygen consumption by mitochondria from a vertebrate source by >98%. 2B). . Different concentrations of Oligomycin (#O-500) were then added (B, 1 µg/ml; C, 2 µg/ml and D, 10 µg/ml). This suggests that ATP was required for the execution of several distinct processes in the apoptotic program. Plates are scanned on a microplate reader at 595 nm. Different concentrations of oligomycin (final concentration 1 or 5 μM) were added to the cells 20 h before the transfection of cells with Apt(ATP)@LIP. As protons move down their concentration gradient, back into the matrix, they spin ATP synthase and ATP is produced.
