Strengths and limitations
- The SUIT-003 O2 ce D012 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).
- When the cell viability test module is not incorporated to the experiment, complex III inhibitors can be used to reach Rox instead of rotenone.
- When MiR05 is used, the addition of pyruvate is recommended to provide an external fuel substrate.
- CIV activity can also be measured after the cell viability test module.
- + With the extended module S-ET capacity can be assessed after the performance of the coupling control protocol, as well as outer mt-membrane integrity with the addition of cytochrome c.
- + Flexibility of experiment duration: from 1 hour (cell coupling control protocol) to 2 and a half hours (cell coupling control, cell viability test module and CIV module).
- - The addition of oligomycin has to be carefully tested to avoid inhibitory effects in the evaluation of the ET-capacity.
- - Careful washing is required after the experiment to avoid carry-over of inhibitors and uncoupler.
