Isothermal Titration Calorimetry
Molecular recognition is key in all biological processes and cellular responses. It is critical to characterize the structural and thermodynamic forces behind the recognition and specificity of macromolecular interactions in order to understand the molecular events in a cell. Several biophysical techniques (including fluorescence, circular dichroism, Fourier transform infrared spectroscopy, mass spectroscopy, surface plasmon resonance, and microscale thermophoresis) are used to characterize non-covalent molecular interactions.
Isothermal titration calorimetry (ITC) has become a popular and versatile bioanalytical method for the direct measurement of binding affinity between interacting molecules.  ITC instruments were …

Binding Affinity
 
Understanding binding affinity is key to appreciation of the intermolecular interactions driving biological processes, structural biology, and structure-function relationships. It is also measured as part of the drug discovery process to help design drugs that bind their targets selectively and specifically.
We recently launched a new short video showcasing the MicroCal PEAQ-ITC and how it is an essential piece to any biological interaction analysis toolkit for measuring Binding affinity and stoichiometry.

The MicroCal PEAQ-ITC offers key benefits over other ITC systems including:

A professional and personal view
If your newsfeed from scientific and mainstream media sources is anything like mine, you have seen numerous articles and blogs about the ‘reproducibility crisis’ in the life sciences.
Well-established cornerstones of scientific inquiry and research are the publication of findings in peer-reviewed journals, along with the opportunity for others to reproduce and verify published data.  This advancement and consolidation of knowledge leads to further understanding on how biological systems work, and provides the basis for the discovery and development of new drugs which benefit all of us.
However, there …

I always enjoy meeting our Malvern customers whenever I travel to different sites and events. I have been assisting customers with MicroCal ITC (Isothermal Titration Calorimetry) and DSC (Differential Scanning Calorimetry) instruments for over 15 years, and there are customers I have known since 2001. Every time I think I “know it all” I always learn something new from our customers, such as a unique sample analyzed using our instruments, or a “trick” for sample preparation or data analysis.
Malvern Instruments recently hosted two MicroCal “User Days” in San Diego, CA …

Thermodynamics – Recap of the 30th Annual Gibbs Conference on Biothermodynamics 
ΔG = ΔH – TΔS
 
Many scientists will recognize this equation, relating the enthalpy and entropy change of a reaction to ΔG or “Gibbs energy.”  But do you know anything about the man behind this expression of energy?
Josiah Willard Gibbs (1839 –1903), spent most of his life in New Haven, Connecticut. His work on the applications of thermodynamics was instrumental in transforming physical chemistry into a rigorous deductive science. Together with James Clerk Maxwell and Ludwig Boltzmann, he created statistical mechanics (a term that Gibbs coined), explaining the laws of thermodynamics as consequences of the …

In a recent blog, I discussed the popularity of Isothermal Titration Calorimetry (ITC) in life sciences research, and cited the increasing number of citations found in Google Scholar searches.
A 2016 review article in Journal of Molecular Recognition by Robert J Falconer, from University of Sheffield (UK), entitled “Applications of isothermal titration calorimetry – the research and technical developments from 2011 to 2015” showed a similar growth of ITC publications.
Between 2003 and 2012, the Journal of Molecular Recognition published annual surveys of ITC research (see links below for the most recent …

Microcalorimetry is hot in Brazil!
In February 2016, I participated in microcalorimetry workshops in Rio de Janeiro and Sao Carlos, Brazil. There is a long-standing and active group of calorimetry users in Brazil, and I had the opportunity to give introductory isothermal titration calorimetry (ITC) and differential scanning calorimetry (DSC) presentations at each workshop. Faculty members and students presented their research projects including ITC and/or DSC results.
 
 
These workshops were coordinated by my Malvern Brazil colleague, Henrique Kajiyama. During our Brazilian tour, Henrique and I had the opportunity to speak to attendees …

Isothermal Titration Calorimetry: An essential tool for binding affinity measurements in life sciences research
What is Isothermal Titration Calorimetry?

Isothermal titration calorimetry (ITC) is established in biophysical characterization circles as the “gold standard” for measuring binding affinity interactions involving proteins, lipids, nucleic acids and other biopolymers.
Since there are so many ways to measure binding affinity, why has Isothermal Titration Calorimetry (ITC ) become the gold standard?
ITC (Isothermal Titration Calorimetry) is a direct, label-free binding assay that measures the heat change due to a binding interaction. Every binding event and chemical process gives off heat (exothermic) …

Here is a short story from one of our customers who works in the field of Structural Biology. He shares his experience from a project where the protein he had purified turned out to be significantly unstable. He discovered that using the MicroCal ITC and DSC systems in combination with Malvern Dynamic Light Scattering (DLS) helped him to uncover the instability issue missed by other techniques and offered an optimal solution for his application.

Structural characterization of H. pylori adherin BabA – Lewisb antigen interaction with X-ray crystallography and Isothermal Titration Calorimetry (ITC)
I recently found an interesting research article about the use of ITC to characterize how H. pylori (the bacterium that causes ulcers and stomach cancer) “works”, and I thought it would make an interesting blog.
It is estimated that the Gram-negative bacterium Helicobacter pylori is present in the stomachs of over half the world’s population.  H. pylori infection can lead to peptic ulceration and it is the highest risk factor for gastric cancer.  The …
