Strengths and limitations
- This protocol serves as a respiratory control (since fluorescence dyes may inhibit components of the ET system) and quality control for the sample for SUIT-026 AmR mt D064.
- + Short protocol.
- + The addition of cytochrome c to assess the mt outer membrane integrity provides a quality control of the sample, which cannot be performed in the protocol with Amplex UltraRed.
- - This protocol does not provide information about all the coupling control states (LEAK, OXPHOS and ET). However, it is possible to create a DLPU by additing an Event&Mark for the uncoupler titration (4U) after ADP (3D) to obtain ET-state.
