AFFINImeter fits with scientific publications

 

Recently we received the great news because AFFINImeter has been used and mentioned in some scientific publications.

The first one, It´s a review of the applications of Isothermal Titration Calorimetry from 2011 to 2015 . The author describes that:

“AFFINImeter produces commercial software that can be used for analysis of displacement assays, micellisation experiments, kinITC, the application of complex models for complex interactions and ligand-induced conformational change.” R. J. Falconer

Most of all publications have used KinITC method and the last one, the authors have used advanced tools like applying complex binding models or working with species distribution plot.

5 Tips to optimize your ITC experiments for kinetic analysis.

Since the method KinITC was implemented in AFFINImeter many researchers have been using it to obtain kinetic information of binding interactions from ITC data; the good news is that no special experimental setup different from the standard ITC experiment is required to register data for kinetic analysis! The information is derived from analysis of the thermogram of regular ITC titrations and therefore one can obtain kinetic information from old ITC data right away.

There are few recommendations though if you are planning to perform new ITC experiments, focused on getting high-quality data for kinetic analysis:

1) Set the time between successive power measurements to 1s or 2s. This will give a better definition of the thermogram peaks and therefore a more precise calculation of the equilibration times.

2) Set the time recording the baseline before the first injection to 1 or 2 minutes. In order to have a good reference when determining the signal baseline.

3) Leave enough time between injections so that a full equilibration for the overall set of injections is registered.

4) Clean thoroughly the instrument before the experiment. This is fundamental to optimize the response time of the instrument, which strongly determines the sensitivity of the kinetic analysis.

5) A high gain feedback mode is recommended in order provide the fastest response time (but, be careful because a high feedback mode can also generate signal overshooting after injection, which greatly difficulties the kinetic analysis! If overshooting happens, don´t use high gain model).

AFFINImeter & ITC: A PERFECT MATCH FOR THE COMPLETE THERMODYNAMIC AND KINETIC CHARACTERIZATION OF MOLECULAR INTERACTIONS:

The use of Biophysical methods for the characterization of molecular interactions has become a fundamental milestone in the area of pharmaceutical research. Into this subject, Isothermal Titration Calorimetry, ITC, is considered the gold standard for the thermodynamic characterization of molecular interactions, but with a potential that has not been fully exploited yet.

Blow the dust off your old ITC binding experiments, you still can get kinetic information out of them

Titration of a

How many experiments have you carried out in your Isothermal Titration Calorimeter during the last years? Do you know that you can reuse them to obtain kinetic information?

 

 

 

KinITC is a methodology recently developed by Philippe Dumas (CNRS, France) to simultaneously get kinetic and thermodynamic information from a standard ITC experiment. The current implementation of kinITC in AFFINImeter is valid only for 1:1 interactions but we intend to extend this for more complex systems in the near future.

 

 

 

kinetics-analysis-in-affinimeter-2
If you have performed experiments of 1:1 interactions in the past, bring them back and use KinITC to get kinetic constants (kon and koff). Under ideal conditions (perfectly clean sample cell, accurate characterization of the response time of your instrument and sufficiently slow kinetics) the resulting values are expected to be equivalent to those obtained by surface plasmon resonance (SPR). The whole process takes just a few seconds and you can analyse multiple files simultaneously.

AFFINImeter guest presenter of the Malvern webinar on advanced Isothermal Titration Calorimetry (ITC) data analysis

Webinar on advanced Isothermal Titration Calorimetry (ITC) data analysis

The AFFINImeter team are guest presenters of the Malvern webinar on advanced Isothermal Titration Calorimetry (ITC) data analysis. Together we will show how the latest advances in the field of ITC data analysis enable users to “squeeze” the ITC isotherm(s) to get more information than just thermodynamic data and to expand the range of applications of ITC. This webinar will be very helpful for ITC users studying complex interactions, for those who are having difficulties with their data analysis, or simply want to take their analysis to the next level. It is of special interest relevant for researchers from academia and industry working in biomedical applications, particularly in the area of drug design.
