Thanks so much Dr. Wayne F Beyer,
I have the absorbance/per unit time, substrate concentration and the amount of enzyme. Can you send me the equation formula that joined all of them in order to calculate the enzyme activity?
How can I extract GA3 (Gibberellic acid) from plant tissue? and how can I determine its concentration quantitatively and qualitatively?
