ADA Kinetic Assay
The assay runs were continued from last week's, 02/05/2013 , calculated values.
The objective of performing the assay is to obtain the rate of the enzymatic reaction of adenosine into inosine by ADA.
Baseline 200-400nm using pH 7.4, 0.05M phosphate buffer
Temperature control: 25°C
Phosphate buffer in reference cell
Ran kinetics on 250uM solution (20uL ADA, 600uL 1250uM Adenosine, and 2.38mL pH7.4, 0.005M phosphate buffer) for 5 minutes at 265nm.
absorbance exceeded 4.00, so the assay was stopped and a new solution was prepared.
Ran kinetics on 2.56uM solution (20uL ADA, 600uL 12.8uM Adenosine, and 2.38mL pH7.4, 0.005M phosphate buffer) for 5 minutes at 265nm.
dAbs was obtained and plotted vs. time in excel
Ran kinetics on 6.4uM solution (20uL ADA, 600uL 32uM Adenosine, and 2.38mL pH7.4, 0.005M phosphate buffer) for 5 minutes at 265nm.
dAbs was obtained and plotted vs. time in excel
Ran kinetics on 16uM solution (20uL ADA, 600uL 80uM Adenosine, and 2.38mL pH7.4, 0.005M phosphate buffer) for 5 minutes at 265nm.
dAbs was obtained and plotted vs. time in excel
The following table describes the volumes and concentrations of the components added to the cuvette.
