1.PrepareNADPstocksolution(100X):
Add100µLofH2OintothevialofNADP(ComponentC)tomake100XNADPstocksolution.
2.PrepareG6PDstocksolution:
Add100µLofH2OorPBSbufferintothevialofG6PDStandard(ComponentD)tomake100U/mLG6PDstandardsolution.
Note:TheunusedG6PDstandardstocksolutionshouldbedividedintosingleusealiquotsandstoredat-20oC.
3.PrepareserialdilutionsofG6PDstandard(0to300mU/mL):
3.1 Add10μLofG6PDstocksolution(fromStep2)into990µLPBSbuffertogenerate1000mU/mlG6PDstandardsolution.
Note:DilutedG6PDstandardsolutionisunstable,andshouldbeusedwithin4hours.
