50uL of purified protein from the first elution was added to 3mL of cold 1mg/mL PNPA at pH=7.30. Chloride ion cofactor was provided by the 2M HCl. A change in absorbance at 428.7nm over time was noted. The time range of the run did not produce a linear response. The absorbance increased for the first ten minutes and plateaued. The time 0 to 10 minutes was used to create the third figure with a more refined linear range. | 50uL of purified protein from the first elution was added to 3mL of cold 1mg/mL PNPA at pH=7.30.
