==Objective==
* A run of 40 μM adenosine with 50 μM varying inhibitors were conducted using the UV 2500 Shimadzu spectrophotometer.
* Three runs of each inhibitor were taken; the average of the runs were taken. The standard deviation were calculated and added as error bars.
* Produce histogram


==Protocol==
* 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
