Ordering Information

Biological Activity

Coenzyme Q10 (ubiquinone) is an essential electron carrier in the mitochondrial electron transport chain and a potent lipophilic antioxidant. It transfers electrons from complex I and complex II to complex III, facilitating aerobic cellular respiration and adenosine triphosphate (ATP) generation. Additionally, coenzyme Q10 scavenges reactive oxygen species (ROS) and inhibits lipid peroxidation in intracellular membranes, maintaining cellular redox homeostasis and organelle integrity. [1][2]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
