Plan, perform and analyze your experiments


switchBUILD & switchCONTROL



switchANALYSIS is a powerful software package designed for the rapid analysis and presentation of switchSENSE® data. From single experiments to large complex datasets, the intuitive drag‘n‘drop format enables quick and efficient data interpretion. switchANALYSIS is fueled by advanced interaction and biophysical modelling providing publication ready graphs and full numerical packages available for export.

Advanced Interaction Analysis

  • Analyze kinetics from real-time association and measurements from simple 1:1 to complex interaction models and determine kinetic rate constants (kON, kOFF) and affinities/dissociation constants (KD) using individual and global fits.
  • Analyze equilibrium dissociation constants or IC50 values from titration curves using straightforward dose-response models, Langmuir, and Hill-fits.
  • Quantify avidity effects through the automated global analysis of measurements at different ligand densities.

Quantitative Biophysical Analysis

  • Measure and analyze protein diameters DH with Angström accuracy and compare experimental data to hydrodynamic calculations from PDB files.
  • Quantify conformational changes in proteins by absolute numbers (diameter in nanometers) including monomers, dimers and multimers.
  • Monitor the enzymatic activity of polymerases and nucleases to determine catalytic rate constants and enzymatic units.
  • Evaluate melting curves of protein for thermal shift assays and the determination of melting points (TM).
  • Extract thermodynamic energies (ΔG, ΔH, ΔS) from integrated van‘t Hoff and Eyring analyses of temperature dependent measurements.

switchBUILD & switchCONTROL


switchBUILD software is an easy-to-use graphical planning tool to design and program experimental workflows.

  • Simply drag’n’drop individual building blocks including “kinetics”, “protein diameter” and “melting” into the measurement queue to create your bespoke workflow.
  • Use the system’s automatic dilution series to reduce hands-on time, improve data quality and accelerate your lab work.
  • Workflow output sheet tells you where to put what in the liquid handling station.
