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.
