Mcl1-conditional mice were injected with AAV-LP1-Cre to delete endogenous MCL-1 and with AAV-LP1-Mcl1Flag (FLINT) or AAV-LP1-GFP (wt control). After 14 days, mitochondria were harvest from mouse livers and subjected to anti-FLAG immunoprecipitation. Immune complexes were subjected to LC MS/MS mass spectrometry. Two independent liver mitochondria immunoprecipitations were run in parallel.
