==Protocol for Assay==
 
* The reagents were added in the following sequence:
 
** 1.78 mL of phosphate buffer
 
** 600 μL of 200 μM adenosine (final concentration 50 μM)
 
* This was allowed to mix through venting and placed on  the chamber for absorbance reading.
 
** 300 μL of phosphate buffer (or inhibitor dissolved in phosphate buffer)
 
** 300 μL of dimethyl sulfoxide (DMSO) (or inhibitor dissolved in DMSO)
 
* The cuvette contents were mixed by venting and placed on the chamber for absorbance reading.
 
** 20 μL of adenosine deaminase (ADA) was added to catalyze the reaction
 
* The kinetics of the reaction was taken using the UVProbe software.
 
  
*Cuvette Mixture no Inhibitor
