Go to CalR, a web application for indirect calorimetry analysis. The CalR project: There is a critical lack of standardization for indirect calorimetry experiments to measure body composition ( Corrigan et al eLife 2020, Banks et al Nature Metabolism 2025). Currently, the same dataset can produce...

Male C57Bl/6J mice housed at thermoneutrality were administered the β-adrenergic agonist CL 316,243, and changes in oxygen consumption were continuously measured. ​

In vivo stable isotope tracing with U-¹³C₆ D-mannitol and U-¹³C₆ D-glucose was conducted to enable ¹³CO₂ monitoring in the Promethion indirect calorimeter, with data plotted using CalR for conventional (blue) and commensal-depleted (red) mice (Vieira et al., in press).
