to baseline UV-vis, have one cuvette of phosphate buffer in reference cell and one cuvette of phosphate buffer in sample cell and run baseline from 200-400nm.
keep the cuvette containing phosphate buffer in the reference cell and put the adenosine + buffer + ADA in the sample cell.
The following table was used to create the mixtures in the cuvette.
In order to complete trail 2, 100uM, 150uM and 200uM [adenosine] were run.
All the listed concentrations were run for trial 3.
