Entry title


Use data collected yesterday to calculate Average values of the Assay and calculate Km


  • All Graphs and Tables are for the Combined Data:

  • For run #2 concentration 40 uM was removed as an outlier
  • For run #1 no values for concentration 150 uM were used
  • Ki values for the inhibitors were found in a paper from Planta Medica:
Flavanoid Ki value)
Myricetin 32 uM
Kaempferol 32 uM
Quericetin 26 uM
