1.PrepareandincubatecellswithApopxin™DeepRed:
1.1 Treatcellswithtestcompoundsforadesiredperiodoftime(4-6hoursforJurkatcellstreatedwithstaurosporine)toinduceapoptosis.
1.2 Centrifugethecellstoget1-5×105cells/tube.
1.3 ResUSPendcellsin200μLofAssayBuffer(ComponentB).
1.4 Add2μLofApopxin™Red(ComponentA)intothecells.
Optional1:Add1µLof200XNuclearGreen™DCS1(ComponentC)intothecellsfornecrosiscells.
Optional2:Add100µLofDMSOintothevialofCytoCalcein™Violet450(ComponentD)tohave200XCytoCalcein™Violet450stocksolution,andthenadd1µLintothecellsforhealthycellsstaining.
1.5 Incubateatroomtemperaturefor30to60minutes(protectedfromlight).
1.6 Add300μLofAssayBuffer(ComponentB)toincreasevolumebeforeanalyzingthecellswithaflowcytometerorfluorescencemicroscope(seeStep1.7below).
1.7 MonitorthefluorescenceintensityatEx/Em=630/660nmforapoptosis,490/520nmfornecrosis,and405/450nmforhealthycellsusingaflowcytometerorafluorescencemicroscope(SeeStep2or3below).
2.Analyzecellsusingaflowcytometer:
QuantifyApopxin™RedbindingbyusingtheFL4channel(Ex/Em=630/660nm),andmeasurethecellviabilityusingtheFL1channel(Ex/Em=490/520nm)whenNuclearGreen™DCS1isadded,and/orusingEx/Em=405/450nmwhenCytoCalcein™Violet450isaddedintothecells.

3.Analyzecellsusingafluorescencemicroscope:
3.1 PipettethecellsuspensionfromStep1.5,rinse1-2timeswithassaybuffer,andthenresuspendthecellswithassaybuffer.Addthecellsonaglassslidethatiscoveredwithaglasscoversliporablackwall/clearbottom96-wellmicroplate.
