1.PrepareNADPstocksolution(100X):
Add100µLofH2OintothevialofNADP(ComponentC)tomake100XNADPstocksolution.
2.PrepareG6PDstocksolution:
Add100µLofH2Oor1xPBSbufferintothevialofG6PDStandard(ComponentD)tomake100U/mLG6PDstandardsolution.
Note:TheunusedG6PDstandardstocksolutionshouldbedividedintosingleusealiquotsandstoredat-20oC.
3.PrepareserialdilutionsofG6PDstandard(0to300mU/mL):
3.1 Add10μLofG6PDstocksolution(fromStep2)into990µL1xPBSbuffertogenerate1000mU/mlG6PDstandardsolution.
Note:DilutedG6PDstandardsolutionisunstable,andshouldbeusedwithin4hours.
3.2 Take15μLof1000mU/mlG6PDstandardsolution(fromstep3.1)into485uLof1xPBSbuffertogenerate30mU/mLG6PD,andthenperform1:3serialdilutionstoget10,3.3,1.1,0.37,0.12,0.04and0mU/mLserialdilutionsofG6PDstandard.
