Applications
Adenosine 5′-monophosphate (AMP) is used in the determination of creatine kinase and 5′-nucleotidase.
Procedure
- Dissolve 50 mg AMP in 50 ml distilled water in a volumetric flask.
- Set spectrophotometer (equipped with strip chart recorder and temperature control) at 340 nm and 25° C.
- Into two cuvettes, pipette the following:
BLANK SAMPLE
Buffer (1) 3.00 ml 3.00 ml
NADH (2) 0.05 ml 0.05 ml
ATP (3) 0.01 ml 0.01 ml
PEP (5) 0.15 ml 0.15 ml
LDH (6) 0.01 ml 0.10 ml
PK (7) 0.02 ml 0.02 ml
Distilled H2O 0.05 ml – – –
Sample – – – 0.05 ml
Mix and read the absorbance A1.
- Start the reaction by adding 0.01 ml myokinase (8) to both the blank and sample. Read the absorbance A2.
