Confirmation of the identity of adenosine in extracts using a chemical standard. A) The extracted ion chromatogram of adenosine in a brainstem extract (red) overlapped with that of an adenosine standard (black), which indicates that they have identical retention times. B) Confirmation of the identity of adenosine by LC/MS/MS analysis. The upper (red) and lower (black) panels show the collision induced dissociation (CID) spectrum of adenosine in a brainstem sample and of an adenosine standard, respectively. The collision energy was set at 28V.
