1.Preparesphingomyelinworkingsolution:
Add50µLofSphingomyelin(ComponentB)to5mLofSMaseReactionBuffer(ComponentD)andmixwell.
Note:Thesphingomyelinworkingsolutionshouldbeusedpromptly.
2.Preparesphingomyelinasestandardsand/orsphingomyelinase-containingsamples:
2.1 Dilutesphingomyelinasesotcksolutionin20mMsodiumacetatebuffer(pH=5.0,notprovidedinthekit).Werecommendtheconcentrationrangefrom10U/mLto0.5U/mL.
Note1:Acidicsphingomyelinasestandard(fromhumanplacenta)isavailablefromSigma-Aldrich(S-5383).
Note2:Dilutedsphingomyelinasestandardsolutionisunstable,andshouldbeusedwithin4hours.
