1.Preparecells:
Plate100to100,000cells/wellinatissueculturemicroplatewithblackwallandclearbottom.Addtestcompoundsintothecellsandincubateforadesiredperiodoftime(suchas24,48or96hours)ina37°C,5%CO2incubator.Forblankwells(mediumwithoutthecells),addthesameamountofcompoundbuffer.Thesuggestedtotalvolumeis100µLfora96-wellplate,and25µLfora384-wellplate.
Note:Eachcelllineshouldbeevaluatedonanindividualbasistodeterminetheoptimalcelldensityforproliferationorcytotoxicityinduction.Forproliferationassays,usefewercells;forcytotoxicityassays,usemorecellstostartwith.
2.Preparedye-loadingsolution:
2.1 Thawoneofeachkitcomponentatroomtemperaturebeforeuse.
2.2 MakeCytoCalcein™Greenstocksolution:Add20µLofDMSO(ComponentB)intothevialofCytoCalcein™Green(ComponentA),andmixwell.
Note:20µLofCytoCalcein™Greenstocksolutionisenoughforoneplate.UnusedCytoCalcein™Greenstocksolutioncanbealiquotedandstoredat<-20oCforonemonthifthetubesaresealedtightly.Protectfromlightandavoidrepeatedfreeze-thawcycles.
2.3 MakeCytoCalcein™Greendye-loadingsolutionforonecellplate:Addthewholecontent(20µL)ofCytoCalcein™Greenstocksolution(fromStep2.2)into10mLofAssayBuffer(ComponentC),andmixwell.Theworkingsolutionisstableforatleast2hoursatroomtemperature.

3.Runthecellviabilityassay:
3.1 Treatcellswithtestcompoundsasdesired(fromStep1).
Note:Itisnotnecessarytowashcellsbeforeaddingcompound.However,iftestedcompoundsareserumsensitive,growthmediumandserumfactorscanbeaspiratedawaybeforeaddingcompounds.Add100µL/well(96-wellplate)and25µL/well(384-wellplate)of1XHank’ssaltsolutionand20mMHepesbuffer(HHBS)orthebufferofyourchoiceafteraspiration.Alternatively,cellscanbegrowninserum-freemedia.
3.2 Add100µL/well(96-wellplate)or25µL/well(384-wellplate)ofdye-loadingsolution(fromStep2.3).
3.3 Incubatethedye-loadingplateatroomtemperatureor37oCfor1hour,protectedfromlight.(Theincubationtimecouldbefrom15minutestoovernight.Wegottheoptimalresultswiththeincubationtimelessthan4hours.)
Note1:Theappropriateincubationtimedependsontheindividualcelltypeandcellconcentrationused.Optimizetheincubationtimeforeachexperiment.
Note2:DONOTwashthecellsafterloading.
Note3:Fornon-adherentcells,itisrecommendedtocentrifugecellplatesat800rpmfor2minuteswithbrakeoffafterincubation.
