Molecular interaction analysis

Service Brief

BiacoreTM, MicroCalTM ITC and MicroCalTM DSC three molecular interaction analysis systems are available To provide unique molecular interaction analysis services according to different needs. efficient, high sensitivity, affordable, AtaGenix is your best choice.

  Affinity is an important parameter for determining the interaction between molecules, and is an important indicator for understanding molecular recognition and biological processes, drug discovery and screening. For the evaluation of drug efficacy, the stability of biomacromolecules and their complexes, etc., it is necessary to conduct a comprehensive study on kinetics, thermodynamics and thermal stability, including the intermolecular binding, the speed and strength of binding, the mechanism of the combination and so on.



BiacoreTM is based on the new biosensing analysis technique developed by physical optical phenomenon called surface plasmon resonance. AtaGenix has two systems, Biacore 8K and Band BiacoreTM T200 (4-channel, 384 continuous injection), which provide superior kinetic testing services.

MicroCalTM ITC200

  Isothermal titration calorimetry (ITC) is the thermodynamic technique that monitors any chemical reaction initiated by the addition of the binding component. For researchers who need to use existing methods for solid phase hardening or use thermodynamic parameters for molecular design of new drugs, BioCalTM iTC200 isothermal titration microcalorimeter can study the interaction between biomacromolecules from thermodynamic, providing the thermodynamic mechanism for the interaction of biological macromolecules.

Type of information

Binding constant, amount of binding sites, molar binding enthalpy, molar binding entropy, molar constant pressure heat capacity and kinetic parameters (eg enzyme activity, enzymatic reaction Michaelis constant and number of enzyme conversions)

AtaGenix Advantages

1. Fast get KD

2. Measuring target activity

3. Confirm the combination of drug and target

4. Using thermodynamics to guide the optimization of lead compounds

5. Confirm IC50 and EC50 values

6. Determination of enzyme kinetics

MicroCalTM DSC

   Differential thermal scanners (DSCs) measure the thermodynamic changes in molecular interactions by increasing or decreasing the temperature to induce changes in the polymer, the preferred technique for characterizing the thermal stability of molecules. MicroCal VP-Capillary DSC provides with the fastest and most accurate identification of the most stable protein and biopharmaceutical candidates.
