- Enzyme kinetics fitterPaste substrate concentrations and initial rates, with or without an inhibitor, and fit Michaelis–Menten, substrate inhibition, Hill, or competitive, uncompetitive, non-competitive and mixed inhibition by non-linear least squares. Get Km, Vmax, Ki, kcat and kcat/Km with errors, a model comparison by AICc, and the Lineweaver–Burk, Eadie–Hofstee and Hanes–Woolf values side by side. #112
- Buffer recipe calculatorChoose a buffer, pH, concentration and volume, and get a recipe: grams to weigh and mL of NaOH or HCl to add, or how much of two forms to mix. Solves the full charge balance with pKa adjusted for temperature and ionic strength, and shows buffer capacity, species and the pH at the temperature you will use it. #113
- Binding curve fitterPaste ligand concentrations with total and non-specific binding, or a titration signal, and fit one site, one site with non-specific binding, two sites, Hill or tight binding with ligand depletion. Get Kd, Bmax and the Hill coefficient with errors, a model comparison by AICc, the Scatchard plot and an IC50 to Ki converter. #114
