    A Reliable Approach to Quantifying Glucose Kinetics

    The primed constant infusion of stable isotope–labeled glucose is a validated and reliable approach for quantifying glucose kinetics. This method makes it possible to explore whole-body glucose homeostasis under a variety of conditions, such as exogenous infusions of glucose, insulin, or other hormones.

    Our sensitive analysis methods allow for accurate quantitation of labeled glucose in plasma with as little as 25–50 µl of sample.

    An Innovative Method for Measuring Glucose Turnover

    We also support deuterium oxide (D₂O) labeling as a powerful alternative for quantifying glucose turnover. 
    Oral D₂O doses label hydrogens during TCA cycle metabolism, enabling direct measurement of gluconeogenesis rates. This technique, validated by Chacko et al. (J Appl Physiol 104:944-951, 2008), expands the toolkit for glucose metabolism research and how deuterium oxide administration can be used to quantitate gluconeogenesis rates in humans.
    For detailed protocols, see our technical paper: Tracer Experiments with Glucose. Additional resources on whole-body deuterium labeling can be found in our section on  Deuteromics.

    Trusted by Leaders in Metabolic Research

    From discovery to submission, we’ve earned the confidence of industry innovators through precision, speed, and scientific depth.

    It wasn't just 'fill out this study concept sheet and we'll send a quote.' They worked with us to design the protocol, suggested key endpoints, and ensured we'd get the best data. It really felt like a partnership."

    I think they’re extremely organized and very on top of sample management. All the interactions that I’ve had with them have been great.

    They've been instrumental—not just helpful, but truly instrumental. Without them, we'd be looking at inferior | alternatives.

    Frequently Asked Questions

    What processes can be measured in glucose kinetics studies?

    Our assays provide data on hepatic endogenous glucose production, glucose disposal rates, whole-body glucose flux, glucose oxidation, gluconeogenesis, and lactate kinetics.

    Which tracers are used in your protocols?

    Examples include 6,6-D₂-glucose for glucose kinetics and euglycemic clamp studies, and [U-13C₆]-glucose for glucose oxidation.

    Do you support alternative approaches beyond infusion methods?

    Yes. We can also determine glucose turnover using oral deuterium oxide (D₂O) labeling, which enables quantitation of gluconeogenesis rates in humans.
