==Aspirin concentration for ADA Kinetic Assay==
* The assay for the concentrations below will be conducted next laboratory period.
==ADA Kinetic Assay for obtaining the zero point==
* The procedure was taken from [[User:Mary Mendoza/Notebook/CHEM572 Exp. Biological Chemistry II/2013/02/20|Mary Mendoza.]]
* The objective of this laboratory period is to conduct adenosine deaminase (ADA) kinetic assay runs for the new calculated concentrations.
* UV 2550 Shimadzu spectrophotometer was baseline with 0.05 M sodium phosphate buffer.
* The assays were prepared according to the data below.
* After running the first trial, it was observed that the absorbance for 12.34 μM adenosine of trial 2 was superimposed over the 10.52 μM adenosine of trial 1.
* It was suggested by Dr. Hartings to use Beer's Law for accurate measurement of the concentration of adenosine in solution.
* An article was provided by Dr. Hartings with the molar extinction coefficient, 1.53 x 10<sup>-4</sup> of adenosine at 260 nm.
* Thus, it was decided to run a full spectrum of adenosine at each given concentration specified above for accurate measurement of  the concentration of adenosine.
