1.PreparingtheStrandBrite™Greenworkingsolution:
1.1 PrepareanaqueousworkingsolutionoftheStrandBrite™Greenbymakinga200-folddilutionoftheconcentratedDMSOsolutioninTE(10mMTris-HCl,1mMEDTA,pH7.5inDEPCtreatedwater).Forexample,add50μLStrandBrite™Greento10mLTEbuffertoprepareenoughworkingsolutiontoassay100samplesina200µLfinalvolume.Protecttheworkingsolutionfromlightbycoveringitwithfoilorplacingitinthedark.
Note1:Werecommendpreparingthissolutioninaplasticcontainerratherthanglass,asthedyemayadsorbtoglasssurfaces.
Note2:Forthebestresults,thissolutionshouldbeusedwithinafewhoursofitspreparation.
2.PrepareserialdilutionsofRNAstandard(0to1µg/mL):
2.1 Preparea100μg/mLstocksolutionofRNAinDEPCtreatedwater.
2.2 Add10μLof100μg/mLRNAstocksolution(fromStep2.1)to490µLofAssaybuffer(ComponentB)tohave2μg/mLRNAsolution,andthenperform1:2serialdilutionstoget1000,500,250,125,62.5,31.3,15.6,and0ng/mL.
2.3 AddRNAstandardsandRNAcontainingtestsamplesintoa96-wellsolidblackmicroplateasdescribedinTables1and2.

3.RundsDNAassay:
3.1 Add100μLofStrandBrite™Greenworkingsolution(fromStep2)toeachwelloftheRNAstandard,blankcontrol,andtestsamples(seeStep3)tomakethetotalRNAassayvolumeof200µL/well.
Note:Fora384-wellplate,add25μLsampleand25μLofStrandBrite™Greenworkingsolutionperwell.
3.2 Incubatethereactionatroomtemperaturefor5to10minutes,protectedfromlight.
3.3 MonitorthefluorescenceincreasewithaspectrofluorometeratEx/Em=490/525nm(cutoffat515nm).
Note:Tominimizephotobleachingeffects,keepthetimeforfluorescencemeasurementconstantforallsamples.
3.4 Thefluorescenceinblankwells(withtheassaybufferonly)isusedasacontrol,andissubtractedfromthevaluesforthosecuvetteswithRNAstandardortestsamples.TheRNAconcentrationofthesampleisdeterminedaccordingtotheRNAstandardcurve.
