2.PrepareMitoLite™NIRdye-loadingsolution:
2.1 Thawallthekitcomponentsatroomtemperaturebeforeuse.
2.2 Add50µLof200XMitoLite™NIR(ComponentA)into10mLofAssayBufferA(ComponentB),andmixthemwell.
Note:Aliquotandstoretheunused200XMitoLite™NIR(ComponentA)at-20oC.Avoidrepeatedfreeze/thawcycles.
3.RunMitoLite™NIRAssay:
3.1 Treatcellswithtestcompoundsforadesiredperiodoftimetoinduceapoptosis,andsetupparallelcontrolexperiments.
ForNegativeControl:Treatcellswithvehicleonly.
ForPositiveControl:TreatcellswithFCCPorCCCPat5-50µMina37oC,5%CO2incubatorfor15to30minutes.
Note:CCCPorFCCPcanbeaddedsimultaneouslywithMitoLite™NIR.Togetthebestresult,titrationoftheCCCPorFCCPmayberequiredforeachindividualcellline.
3.2 RemovethecellmediumbeforeaddingMitoLite™NIRdye-loadingsolution(SeeStep3.3).
