title: A general method of curve fitting and error analysis using a spreadsheet: determination of the binding constants of tight binding ligands in variable volume assays.
abstract: A generalized iterative method of curve fitting and error estimation is described, using a spreadsheet with Monte Carlo simulations. The method is demonstrated on an equilibrium binding experiment with reverse transcriptase of human immunodeficiency virus-1, in which the concentration of all reactants, including enzyme, can vary arbitrarily and any number of ligands can bind tightly.
