Metabolic research unit is designed to provide an array of sophisticated research techniques from animal model to cell biology to the scientific community. TSE metabolic cages are capable to record mouse metabolic, behavioral and physiological activity automatically. Vitros 250 chemical analyzer is capable of accurately and quantitatively measuring 36 analytes, including glucose, cholesterol, triglyceride, sodium and et al. in serum, plasma, urine, or other biological fluid. The XFe-24 flux analyzer allows real time monitoring the media flux (oxygen consumption rate (OCR) and extracellular acidification rate (ECAR)) to study the metabolic status at cell and tissue level.
