Microcalorimeters for characterization of biomolecular stability and interactions
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.
MicroCal microcalorimeters are used in a wide range of applications from basic research to the discovery and development of small molecule drugs, biotherapeutics and vaccines. Our customers include pharmaceutical, biotech, academic and governmental research institutions worldwide.
MicroCal DSC microcalorimeters are powerful analytical tools for characterizing the stability of proteins and other biomolecules, requiring minimal assay development, no labelling or immobilization. The automation and high sensitivity afforded by MicroCal VP-Capillary DSC systems permits screening of large numbers of samples at low concentrations minimizing the consumption of valuable samples with little hands-on effort.
MicroCal ITC isothermal titration calorimeters are used to study a wide range of biomolecular interactions. The applications range from drug design to fundamental research such as the understanding and regulation of signal transduction pathways. These systems deliver direct, label free and in-solution measurements of binding affinity and thermodynamic parameters in a single experiment. They have high sensitivity, low sample consumption and options for automation to minimize ‘hands on’ time. A choice of instruments ensures that MicroCal ITC calorimeters meet the varied and demanding requirements of today’s life science laboratories.
