1.Prepare250XMUPPlus™stocksolutions:
Add100µLofsterileH2OintothevialofMUPPLus™(ComponentA).TheMUPPLus™stocksolutionshouldbeusedpromptly.Anyremainingsolutionshouldbealiquotedandrefrozenat-20oC.
Note:Avoidrepeatedfreeze-thawcycles.
2.Prepareassayreactionmixture:
Prepareassayreactionmixtureaccordingtothefollowingtableandkeepfromlight.
Table1Assayreactionmixtureforone96-wellplate
Components | Volume |
MUPPlus™(250X,fromStep1.1) | 20μL |
AssayBuffer(ComponentB) | 5mL |
Totalvolume | 5mL |
Note:Preparefreshreactionmixtureforeachexperiment.
3.Prepareseriallydilutedalkalinephosphatasestandards(0to100mU/mL):
3.1 Add100μLofdistilledH2Owith0.1%BSA(H2O-0.1%BSA)toalkalinephosphatasestandard(ComponentC,10units)togeneratea100units/mLalkalinephosphatasestandardsolution.
Note:Thealkalinephosphatasestandardsolutionisnotstable.Aliquotandstoreunusedsolutionat‑ 20 oC.Avoidrepeatedfreeze-thawcycles.
3.2 Add10μLof100units/mLalkalinephosphatasestandardsolution(fromStep3.1)into990µLofH2O-0.1%BSAtogeneratea1,000mU/mLalkalinephosphatasestandardsolution.
3.3 Take100μLof1,000mU/mLsolution(fromStep3.2)toperform1:10andthen1:3serialdilutionstoget100,30,10,3,1,0.3,0.1,and0mU/mLserialdilutionsofalkalinephosphatasestandard.
3.4 Addseriallydilutedalkalinephosphatasestandardsand/oralkalinephosphatasecontainingtestsamplesintoasolidblack96-wellmicroplateasdescribedinTables2and3.
Note1:Preparecellsortissuesamplesasdesired.
Note2:Unusedportionofdilutedalkalinephosphatasestandardsolutionshouldbediscarded.

4.Runalkalinephosphataseassayinsupernatants:
4.1 Add50μLofassayreactionmixture(fromStep2)intoeachwellofalkalinephosphatasestandard,blankcontrol,andtestsamples(seeStep3.4,Table3)togetthetotalalkalinephosphataseassayvolumeof100µL/well.
Note:Fora384-wellplate,add25μLofsampleand25μLofassayreactionmixtureintoeachwell.
4.2 Incubatethereactionatthedesiredtemperaturefor10to30minutes,protectedfromlight.
4.3 MonitorthefluorescenceincreasewithafluorescenceplatereaderatEx/Em=360±10/450±10nm.
5.Runalkalinephosphataseassayincells:
5.1 Treatthecellsasdesired.
5.2 Addequalvolumeofassayreactionmixture(fromStep2)intoeachcellwell(suchas100μL/96-wellplate,or50μL/384-wellplate).
Note:Alternatively,removethegrowthmediumfromthecellplate,andmake1:1dilutionofthe5mLassayreactionmixture(fromStep2,Table1)with5mLdistilledH2O.ThenAdd100μL(fora96-wellplate)or50uL(fora384-wellplate)of1:1dilutedassayreactionmixtureintothecellwells(fromStep5.2).
5.3 Incubatethereactionatthedesiredtemperaturefor30to60minutes,protectedfromlight.
