Continuous Monitoring/Kinetic assays are defined by which feature?

• A. Continuous measurement as a function of time
• B. Reaction is stopped and measured
• C. Measures at several intervals
• D. Single value at end

Answer: (A)

Continuous monitoring and kinetic assays hinge on tracking the signal in real time as the reaction proceeds, producing a signal-versus-time curve. This time-dependent data lets you determine the reaction rate from the slope and observe how the process evolves, not just the final outcome. Stopping the reaction and taking a single measurement yields an endpoint value, which misses the progress information that defines kinetic measurements. Measuring at several discrete intervals can provide time data, but true continuous monitoring implies data are captured without breaks throughout the reaction.
