Determination of AMP in the rat heart using skeletal muscle AMP deaminase
Analytical Biochemistry
|May 1, 1986
Abstract:
A new simple enzymatic method for measuring AMP content in freeze-clamped rat heart is presented. The method is based on the ammonia estimation after the deamination of 5'-AMP by muscle 5'-adenylic acid deaminase. The minimum detectable amount of AMP was about 1.5 nmol. The recovery of AMP added to the tissue homogenate was 94%. The variance coefficient evaluated by assaying five samples from one tissue extract was equal to 5%. AMP content of rat heart (0.28 mumol/g wet tissue) is comparable with the values reported by others.
