MicroCal microcalorimeters are powerful, analytical tools used to study biological systems. These include interactions between molecules as well as changes in conformation such as protein unfolding. The technique is very convenient requiring only minimal assay development and no labelling. The range includes both Differential Scanning and Isothermal Titration calorimetry.

The NEW MicroCal PEAQ-DSC – the gold standard for thermal stability determination
Differential scanning calorimetry (DSC) is an established biophysical tool for protein stability characterization during drug development. DSC data are used to advance the most stable and ‘developable’ proteins into the pipeline, and optimize the process and formulation conditions which will maintain protein stability during manufacturing and storage. DSC data are also important in higher order structure (HOS) protein characterization, lot-to-lot comparability, and characterization of biosimilar drugs compared to innovators.
Our previous technology, the MicroCal VP-Capillary DSC Automated system, is a …

My introduction to Differential Scanning Calorimetry (DSC) was a postdoctoral fellow in the late 1980s.  I was producing mutant forms of the enzyme thymidylate synthase, and I needed to characterize the effects amino acid changes had on the overall stability of the protein.  Using a DSC instrument at our facility, I compared the thermal stability of the different mutants to wild-type protein by ranking the thermal transition temperature (TM). As I recall, I needed about 2 mg -4 mg protein per DSC experiment, which was a lot of protein at …

DSC for the regulated environment

Advancing biotherapeutic molecules along the drug development pipeline is a complex, time-consuming and expensive process. Good stability is key to a candidate’s progression, and must be assessed and reviewed throughout development – from candidate selection, through formulation development, all the way to batch-to-batch comparability or biosimilarity assessment….and beyond! Objective, reliable stability data is needed for confident decision-making about which drug products and processes to move through development into commercialization.
Differential Scanning Calorimetry (DSC) is a biophysical tool for protein stability characterization. The MicroCal VP-Capillary DSC system, launched in 2002, …

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.

Thermodynamics – Recap of the 30th Annual Gibbs Conference on Biothermodynamics 
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 …

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 …

During the development of proteins for use as biopharmaceuticals, the primary structure (amino acid sequence) is important in defining protein activity. Due to the complex nature of protein drugs, compared to small molecule drugs, biophysical techniques are important tools in the characterization of the protein’s higher-order structure (HOS) to understand the protein’s stability, folding, structure, and functional activity. HOS is characterized by a variety of biophysical methods including:

Mass spectrometry (MS)
Circular dichroism (CD)
Fourier transform infrared spectroscopy (FT-IR)
Raman spectroscopy
X-ray crystallography
Nuclear magnetic resonance (NMR)
Near-UV CD
Size exclusion HPLC
Static and dynamic light scattering (SLS and …

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) …
