SUIT-003 O2 ce D037 has been designed to study the coupling control state and respiration regulation by glucose (Crabtree effect) of intact cells on ROUTINE. To obtain more information about Crabtree effect, this protocol can be used in parallel with SUIT-003 O2 ce D038. SUIT-003 O2 ce D037 follows a modular approach and can be easily used in combination with the assessment of complex IV capacity and respirometric cell viability test.

Strengths and limitations
- The SUIT-003 O2 ce D037 is a cell coupling control protocol. The total cell count (Nce) is the sum of viable cells (Nvce) and dead cells (Ndce).
- This protocol can be extended with the cell viability test module (See CCV SUIT-003 O2 ce-pce D020).
- CIV activity can also be measured after the cell viability test module.
- + Reasonable duration of the experiment.
- + To obtain more information about Crabtree effect, this protocol can be used in parallel with SUIT-003 O2 ce D038. In SUIT-003 O2 ce D037, the addition of glucose during ROUTINE state can lead to increase in ATP production by glycolysis, which can indirectly decrease respiration. In SUIT-003 O2 ce D038, with addition of glucose in ET state, this effect is bypassed, and only the direct effect of glucose on the electron-transfer system is tested.
- - Cell culture media with glucose (e.g. DMEM: 25 ยตM glucose) could hinder the cell viability test.
- - Careful washing is required after the experiment to avoid carry-over of uncoupler.
Compare SUIT protocols
- SUIT-003 O2 ce D038 can be used in parallel to obtain more information on Crabtree effect.
- SUIT-003 O2 ce-pce D013 for assessment of coupling control, Crabtree effect and cell viability test.
- SUIT-003 O2 ce-pce D018 for assessment of coupling control, Crabtree effect, malate effect and cell viability test.
