Advanced Kinetic Analysis Using a LAMBDA Series Spectrometer
... In simple routine tests in practice often only 2 - 5 data points are collected per experiment. In more sophisticated enzyme studies it is recommended to take between 10 and 20 data points, which will allow a more precise linear regression analysis, when using a computerized system. For example, when ...
