Exam Mol 3008 – May 2009 Subject 1 (15p) ALP (alkaline phosphatase) calibrators were analyzed manually in microtiter plates to find the linearity range by following this protocol: Reaction solutions: • 50 μl of calibrator/control/sample is added to each microtiter plate well, duplicates. • 50 μl of buffer-substrate reagent is added to all wells. Start the timer when adding reagent to the first well. • Cover the wells with parafilm, and put the microtiter plate into a 37 ...
