2.PrepareRhod-4NWdye-loadingsolution:
2.1 Thawallthekitcomponentsatroomtemperaturebeforeuse.
2.2 MakeRhod-4NWstocksolution:Add200µLofDMSOintothevialofRhod-4NW(ComponentA),andmixthemwell.

2.3 Make1Xassaybuffer:
a).ForCat.#36334(10plateskit),make1Xassaybufferbyadding9mLofHHBS(ComponentC)intothebottleof10XPluronic®F127Plus(1mL,ComponentB),andmixthemwell.
b).ForCat.#36335(100plateskit),make1Xassaybufferbyaddingthewholebottleof10XPluronic®F127Plus(10mL,ComponentB)into90mLofHHBSbuffer(notincludedinthekit),andmixthemwell.
Note:10mLof1Xassaybufferisenoughforoneplate.Aliquotandstoreun-used1Xassaybufferat<‑20 oC.Protectfromlightandavoidrepeatedfreeze-thawcycles.
2.4 MakeRhod-4NWdyeloadingsolutionforonecellplate:Add20µLofRhod-4NWstocksolution(fromStep2.2)into10mLof1Xassaybuffer(fromStep2.3),andmixthemwell.Thisworkingsolutionisstableforatleast2hoursatroomtemperature.
3.Runcalciumassay:
3.1 Add100µL/well(96-wellplate)or25µL/well(384-wellplate)ofRhod-4NWdye-loadingsolution(fromStep2.4)intothecellplate.
Note:Alternatively,growthecellsingrowthmediumwith5to10%FBStoimprovecellgrowth.Inthiscase,itisimportanttoreplacethegrowthmediumwithHHBSbufferinordertominimizebackgroundfluorescence,andcompoundinterferencewithserum.[Weoffer2separatenowashcalciumassaykits(Cat.#36331and36332)forpeoplewhoprefertokeepthemediumremovalstep].
3.2 Incubatethedye-loadingplateinacellincubatorfor30minutes,andthenincubatetheplateatroomtemperatureforanother30minutes.
Note1:Iftheassayrequires37oC,performtheexperimentimmediatelywithoutfurtherroomtemperatureincubation.
Note2:Ifthecellscanfunctionwellatroomtemperatureforlongertime,incubatethecellplateatroomtemperaturefor1-2hours.
3.3 PreparethecompoundplatewithHHBSoryourdesiredbuffer.
3.4 RunthecalciumfluxassaybymonitoringthefluorescenceintensityatEx/Em=540/590nm.
