New Advances in Fitting Kinetic and Equilibrium Data by Simulation

Kenneth A. Johnson, Ph.D. President, KinTek Corporation, and Roger Williams Professor of Biochemistry, University of Texas at Austin.

Fitting kinetic data based upon numerical integration of rate equations offers many advantages over conventional fitting of data based upon equations derived from simple models. Fitting by simulation is the most rigorous metod, and eliminates the need to derive equations; however, it also requires and understanding of the kinetics, and critical thought to avoid overly complex models. In this presentation, Dr. Johnson will show how global fitting of kinetic data can be accomplished with ease using the fast, dynamic simulation in KinTek Explorer software, overcoming the all-to-common errors in conventional fitting. Moreover, data are fit to derive rate constants directly defining steps in a model. New advances in the software allow fitting kinetic data from single molecule experiments and families of curves can be fit simultaneous to define voltage-dependent rate constants or data from Temperature-jump or Pressure-jump experiments. In addition, equilibrium titration data can be fit using a unique endpoint simulation method, and time-resolved spectra can be fit using singular value decomposition (SVD). Moreover, all experiments can be fit simultaneously.

KinTek Explorer Version 4.0 Has Been Released

KinTek Explorer is the fastest and most powerful software for fitting kinetic and equilibrium data. Fitting is based on a user-defined model and numerical integration of rate equations to allow fitting of primary data directly to the model of interest with no simplifying assumptions. Version 4.0 of KinTek Explorer includes several novel features, including temperature-dependent rate constants and voltage-dependent rate constants (for voltage gated ion channels). In each case, a family of curves can be fit to derive a single set of rate constant at a reference temperature (or voltage) and a set of activation energy (or partial gated charge) terms. In addition, we have increased the capabilities of the Student version to allow the opening and saving of any mechanism file and the ability to export synthetic data. Download the software here. Explore the free student version and order a license for KinTek Explorer to begin fitting your own data. You will be able to import, analyze, and save your own data and analyses.
