Fixed time assay vs kinetic assay
WebScience Biochemistry Briefly comment on the differences of using a fixed-time assay versus a kinetic assay to measure enzyme activity. Is it reasonable to assume that the reaction velocity obtained by measuring the amount of product after 30 minutes in a fixed-time assay is directly proportional to absorbance? WebThe standard approach to measuring kinetic constants in Michaelis-Menten kinetics requires measuring the initial rate of the reaction. The reason is simply so that you can accurately state the...
