Does your sample display a preference for glutamate & malate over pyruvate & malate to support NADH-linked respiration?

DatLab 7.4 provides a step-by-step guide through SUIT-008 and SUIT-014, which can be used in parallel to evaluate the contribution of different combinations of two NADH-linked respiration substrates.

Do you know how to evaluate fatty acid oxidation (FAO, F-pathway) avoiding to overestimate it?

Did you know that malate alone might support mt-respiration in mitochondrial preparations, if malate anaplerotic pathways (e.g. mt-malic enzyme) are present?
- Learn more about - »malate-anaplerotic pathway control state«
- DatLab 7.4 provides a step-by-step guide through the SUIT-027 to evaluate the malate anaplerotic pathway - »SUIT-027«
- Since F-pathway can be overestimated due to anaplerotic reactions, SUIT-002 was specially designed to give information on F-pathway in OXPHOS state avoiding FAO overestimation in the presence of anaplerotic pathways - »SUIT-002«
