Objective

  • to run ADA kinetics assay

Methods

  • Baseline 200-400nm using pH7.4, 0.005M 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
